I recently found myself idly wondering what the shortest Star Trek episode title was. The first to come to mind was the Original Series episode “Arena” (the one which Captain Kirk fights a humanoid lizard in one of the most striking examples of 1960 “makeup”).

I guessed there were probably shorter ones, but was rather disappointed I didn’t know the answer for sure. So I decided to find out.

While investigating, I also started wondering other things, like: what is the longest episode title? Which series has the shortest or longest titles on average? How many episodes begin with “the”?

I have decided to gather the answers to these questions and more together into a series of blog posts.

Some ground rules

I quickly realised even for “shortest episode title” there were some decisions I would have to make about what would count.

What counts as a letter?

Any character is a letter. So including (but not necessarily limited to):

• The letters A-Z (regardless of case or accents).
• The digits 0-9.
• Any punctuation symbol.
• A space.
• An ellipsis (so three dots … is a single character).

What counts as a word?

Spaces separate words, nothing else does. 37's is one word, as is 11001001.

Which series/episodes are included?

I decided to include all episodes from The Original Series (including “The Cage”), The Animated Series, The Next Generation, Deep Space Nine, Voyager and Enterprise. This is for the simple practical reason that no more episodes are being produced for these (with the recent annocunement that season 5 of Discovery will be its last, I may redo this including Discovery in the near future).

What about two-part episodes?

For two part episodes (that don’t have completely different titles), I’m just using the “base name”.

About those two-part episodes

The first two-part episode of Star Trek was called “The Menagerie”. In the episode title sequence it is styled as "THE MENAGERIE" PART I and "THE MENAGERIE" PART II, with the part information clearly outside the quotation marks used to identify the title. This suggests the title is in fact “The Menagerie”.

“The Menagerie” (as far as I am aware) was never produced as a single feature length episode. Many other two-part episodes were either broadcast originally as a single episode, or later made available as one (often with additional footage included). This means an episode could potentially have three different names (one for each part individually and one for the whole) and using the “base name” seems most sensible in this case.

It should also be noted, there is little consistency in how the two-part episode titles are handled. Some of them give the first part the “base name” and add “Part II” after whereas others include the part information in both titles. Whether the part information is inside the quotes varies, and even whether the word “part” is included.

So overall, I feel justified in in using the “base name”, just as a way of establishing some kind of order. Although I can already tell I’m going to have to write a detailed blog post covering all of this (especially if I get to including Discovery, since that messes everything up by having an episode titled as if it is the third part of a three-part episode, the first two parts of which are from another series).

After starting my previous post with this question but not answering it, I’ll get straight to the point. There is a tie for first place, with two episode titles that are two characters long:

Longest episode titles

Unlike with the shortest episode title, I had a good idea what the longest one was. At least, I had two candidates, but without sitting down and counting, picking one would have been a guess. I can confirm they are the longest two, and I present them both since they are such outliers compared to the rest.

Title	Length	Series	Episode
For the World is Hollow and I Have Touched the Sky	50 letters	The Original Series	3x10
Looking for par’Mach in All the Wrong Places	44 letters	Deep Space Nine	5x03

And the longest per series:

Title	Length	Series	Episode
For the World is Hollow and I Have Touched the Sky	50 letters	The Original Series	3x10
How Sharper Than a Serpent’s Tooth	34 letters	The Animated Series	2x05
Where No One Has Gone Before	28 letters	The Next Generation	1x06
Looking for par’Mach in All the Wrong Places	44 letters	Deep Space Nine	5x03
The Haunting of Deck Twelve	27 letters	Voyager	6x25
Two Days and Two Nights	23 letters	Enterprise	1x25

This brings us our first controversial result. I decided that ellipses should be treated as a single letter (if only for a sense of typographical superiority). In this case, treating it as three letters would produce a different result:

Title	Length	Series	Episode
These Are the Voyages…	24 letters	Enterprise	4x22

The titles so far have been longest by letter-count. Longest by word-count can also be determined. This gives identical results, except Voyager and the Animated Series now have ties:

Title	Length	Series	Episode
For the World is Hollow and I Have Touched the Sky	11 words	The Original Series	3x10
One of Our Planets is Missing	6 words	The Animated Series	1x03
How Sharper Than a Serpent’s Tooth	6 words	The Animated Series	2x05
Where No One Has Gone Before	6 words	The Next Generation	1x06
Looking for par’Mach in All the Wrong Places	8 words	Deep Space Nine	5x03
The Q and the Grey	5 words	Voyager	3x11
Someone to Watch Over Me	5 words	Voyager	6x25
The Haunting of Deck Twelve	5 words	Voyager	5x22
Two Days and Two Nights	5 words	Enterprise	1x25

Existing work

Firstly, after doing this much work, I have discovered someone already has done a similar investigation: How long is a Star Trek title? by Bruce Bennett, so check that out. One thing it does have that I don’t, is charts.

Improving workflow

The analysis so far has been done using a Google Docs spreadsheet. I then manually wrote the Markdown for the blog posts, which involved some tedious and error prone tables.

I was originally not going to include the giant list of every single-word episode title, since creating that table did not look like fun.

But… I also started working a little program to do more sophisticated processing, and realised I could also make the program generate the Markdown for me.

The program is a .NET 7 console application writen in C#, and writing it was probably quicker than the manipulation I had to do with the spreadsheet in the first place. It was definitely quicker than producing the Markdown tables in the first post manually.

The end result is I can generate tables of all sorts of random episode lists with different properties of varying levels of interest with very little effort.

My earlier post included a list of all single-word episode titles. That list is long enough that it could be analyzed in isolation and still produce some interesting results. Firstly, here is a summary:

Series	TOS	TAS	TNG	DS9	VOY	ENT
Total	5	3	49	42	77	42
Percentage	6.33 %	13.64 %	29.17 %	24.71 %	48.13 %	44.68 %

Average	7.6	7.33	7.96	8.1	7.81	7.79

Single-word titles by Series

It seems the number of single-word episode titles started low and increased over time, peaking with Voyager (although Enterprise was very close behind by percentage of total episodes).

The Original Series

The original Star Trek is the only series to have a season with no single-word titles at all (and it has two if you follow the convention that the original pilot, “The Cage” is part of its own “Season 0”).

Many titles from the original series were intentionally unusual, in the hope it would generate interest from people browsing TV listings (as explained more by Bruce Bennett). This generally led to longer titles and is part of the reason there are so few with just one word.

The Next Generation

TNG was clearly a transition point in the history of Star Trek. It was obviously more modern and naturally led into the later series with most of the new production staff staying with Star Trek.

It was also still led by Gene Roddenberry early on, along with some of the original writers. This meant that although there were a plenty of long and unusual titles, the preference for simpler ones was becoming established.

Looking at the list of titles we can see TNG has the first that might stretch the definition of “single word”, and that maybe 11001001 is not even be a word. By my established definition though, it counts.

Deep Space Nine

DS9 followed a similar pattern to TNG. Many single-word titles, but plenty of longer ones too.

It also has another title that is questionable as a single word (that is yet another Q pun) in Q-Less.

Voyager

By the time Voyager was written, the preference for single-word titles is well established, peaking in season 2 in which 20 out of 26 have only one word, and includes two separate runs of seven consecutive episodes with single-word titles.

There is another Q pun with Q2 and a bit of controversy with 11:59.

Enterprise

Enterprise titles continue the trend set in Voyager, despite dipping slightly.

If you wanted to be picky you might question the single-word status of Kir’Shara since not only does it contain an apsotrophe, but also a capital letter in the middle.

What about “the”

My anlysis has so far treated a leading “the” as a word. Repeating this while ignoring “the” may produce interesting results, and at the very least will increase the count in Voyager season 2.

Ions

Finally, while browsing the list one interesting pattern stood out. There are 8 episode titles ending in “ions”, including the longest Transfigurations, and a further 22 ending in “ion”.

Sadly, there are none from the animated series.

With nearly 700 episodes, there were bound to be some that are similar to each other. But which are most similar? And what do we mean by similar?

Summary

Before I go into the more technical analysis, I shall begin with some headlines.

Not technically part of this analysis but there are two Star Trek movies that share a title with an episode (if you ignore the “Star Trek” part of the title):

Title	Series	Episode	Title
First Contact	TNG	4x15	Star Trek: First Contact
Nemesis	VOY	4x04	Star Trek Nemesis

There are three pairs of titles that differ by only one character. Two of them are just a final “s” as part of a plural:

Title	Series	Episode	Title	Series	Episode
The Survivor	TAS	1x06	The Survivors	TNG	3x03
Facets	DS9	3x25	Faces	VOY	1x14
Demon	VOY	4x24	Demons	ENT	4x20

There are three pairs of titles that differ only by a leading “the”:

Title	Series	Episode	Title	Series	Episode
The Eye of the Beholder	TAS	1x15	Eye of the Beholder	TNG	7x18
The Emissary	TNG	2x20	Emissary	DS9	1x01
The Muse	DS9	4x21	Muse	VOY	6x22

One of the more significant lines in Star Trek has both its variations appear as titles:

Title	Series	Episode	Title	Series	Episode
Where No Man Has Gone Before	TOS	1x01	Where No One Has Gone Before	TNG	1x06

There is also a TNG episode that is specifically a sequel of sorts to an earlier episode with a similar title:

Title	Series	Episode	Title	Series	Episode
The Naked Time	TOS	1x06	The Naked Now	TNG	1x03

A pair of episodes with weirdly similar titles, but in a way that isn’t easy to define:

Title	Series	Episode	Title	Series	Episode
Beyond the Farthest Star	TAS	1x01	Far Beyond the Stars	DS9	6x13

There is an interesting prefix that appears three times in TNG, and only in TNG:

Title	Series	Episode
A Matter of Honor	TNG	2x08
A Matter of Perspective	TNG	3x14
A Matter of Time	TNG	5x09

Four incidents worthy of naming:

Title	Series	Episode
The Terratin Incident	TAS	1x11
The Counter-Clock Incident	TAS	2x06
The Enterprise Incident	TOS	3x04
The Andorian Incident	ENT	1x07

Technical details

Below I present the top 10 pairs of similar episodes, with four different measures of similarity:

• Levenshtein distance - Informally, the number of single character edits needed to change one title into another.
• Prefix - The number of characters at the start of the titles that are in common (ignoring case).
• Suffix - The number of characters at the end of the titles that are in common (ignoring case).
• Contains - If one title is contained entirely within another (possibly at the start or end), then the length of the contained title (0 otherwise).

Additionally each one is presented with an absolute version, and another normalized to the length of the longest title.

Star Trek Picard season three has just completed. It was not perfect but was probably the best live action Star Trek since Enterprise.

In honor of this, here is a quick analysis of the episode titles.

I’m not including Picard in the main analysis for consistency for now. There is also a small chance there may be more episodes (or possibly something else #StarTrekLegacy).

Title length

Picard does not challenge for overall shortest or longest title.

Shortest

Title	Length	Episode
Võx	3 letters	3x09

Like other series, it has several single word titles:

Title	Length	Episode
Remembrance	11 letters	1x01
Nepenthe	8 letters	1x07
Penance	7 letters	2x02
Assimilation	12 letters	2x03
Watcher	7 letters	2x04
Monsters	8 letters	2x07
Mercy	5 letters	2x08
Farewell	8 letters	2x10
Disengage	9 letters	3x02
Imposters	9 letters	3x05
Dominion	8 letters	3x07
Surrender	9 letters	3x08
Võx	3 letters	3x09

Longest

Title	Length	Episode
The End is the Beginning	24 letters	1x03

Title	Length	Episode
The End is the Beginning	5 words	1x03
Fly me to the Moon	5 words	2x05

Single word titles

The overall single word title stats are very similar to Enterprise.

Series	Enterprise	Picard
Total	42	13
Percentage	44.68 %	44.83 %
Shortest	2	3
Longest	12	12
Average	7.79	8

See comparison with other series'

Series	TOS	TAS	TNG	DS9	VOY	ENT	PIC
Total	5	3	50	42	77	42	13

Longest	13	10	16	12	14	12	12
Average	7.6	7.33	7.92	8.1	7.81	7.79	8

When split by season there is a lot variation though. I expect this to be true of most Star Trek series after Enterprise - the seasons are generally shorter and the serial nature means there are more likely to be patterns within seasons that don’t hold between them.

Season	1	2	3
Total	2	6	5
Percentage	22.22 %	60.00 %	50.00 %
Shortest	8	5	3
Longest	11	12	9
Average	9.5	7.83	7.6

Ionic episodes

Two new “ion” titles (but no “ions”):

Title	Length	Episode
Assimilation	12 letters	2x03

While doing other more systematic investigations of Star Trek episode titles, I made notes of interesting things I spotted.

Here are some collections of episode titles with interesting characters.

Q puns

Most episodes featuring Q had a pun in the title:

Title	Series	Episode
Hide and Q	TNG	1x11
Q Who?	TNG	2x16
Deja Q	TNG	3x13
Qpid	TNG	4x20
True Q	TNG	6x06
Q-Less	DS9	1x07
The Q and the Grey	VOY	3x11
Q2	VOY	7x19

Title	Series	Episode
Encounter at Farpoint	TNG	1x01
Tapestry	TNG	6x15
All Good Things…	TNG	7x25
Death Wish	VOY	2x18

Interestingly, Q has so far made a further appearance in Lower Decks and nine in Star Trek Picard, and none of them had puns in the title.

Containing -

Several episode titles contain a hyphen. One episode contains two. The producers and/or writers probably intended an em dash or similar but were likely limited to hyphens for technical reasons.

After investigating Star Trek episode titles with interesting characters, lets look at ones with interesting words.

Numbers

I already included this as a side note in the previous post, but many episodes have numbers as words, with each series having at least one.

Title	Series	Episode
The Galileo Seven	TOS	1x13
One of Our Planets Is Missing	TAS	1x03
Angel One	TNG	1x15
One Little Ship	DS9	6x14
One	VOY	4x25
Thirty Days	VOY	5x09
One Small Step	VOY	6x08
The Haunting of Deck Twelve	VOY	6x25
Friendship One	VOY	7x21
Shuttlepod One	ENT	1x16
Two Days and Two Nights	ENT	1x25
First Flight	ENT	2x24
Babel One	ENT	4x12

Ordinals

Title	Series	Episode
First Contact	TNG	4x15
The Nth Degree	TNG	4x19
The First Duty	TNG	5x19
Second Chances	TNG	6x24
Second Sight	DS9	2x09
Second Skin	DS9	3x05
The Seventh	ENT	2x07
First Flight	ENT	2x24

Non-English words

This is probably the collection that caused me the most difficulty in deciding what should be included.

I settled on:

• Actual words (no 11:59 or E²)
• Real word languages
• Not proper nouns (especially names of characters)

Considering all that, there are in fact only two non-English languages used in the titles of Star Trek episodes:

French

Title	Series	Episode
The Menagerie	TOS	1x15
Ménage à Troi	TNG	3x24
Vis à Vis	VOY	4x20

Latin

Title	Series	Episode
Sub Rosa	TNG	7x14
Dramatis Personae	DS9	1x18
Inter Arma Enim Silent Leges	DS9	7x16
Non Sequitur	VOY	2x05
Terra Nova	ENT	1x06
Vox Sola	ENT	1x22
Terra Prime	ENT	4x21

Honorable mentions

One Klingon word, and one Vulcan word that is only probably a proper noun.

Title	Series	Episode
Looking for par’Mach in All the Wrong Places	DS9	5x03
Kir’Shara	ENT	4x09

Character names

Who has the privilege of being named in an episode title? Again, there are surprising edge cases so I’ve split it up into several groups.

• Q appears in the most titles.
• Two titles mention two characters: Datalore and Ménage à Troi (which I assumed, in the spirit of the episode, is a reference to both Deanna Troi and Lwaxana Troi).

Direct character references
