Make Your Editor Cry:  Specific Letters as Words or Word Parts

You may wonder whether words like T-shirt and A-frame which amount to a letter combined with a word have an official type or designation. Maybe you don’t and this never made you curious. Personally, I wondered. Are these types of words rightly called initialisms, acronyms, abbreviations, trademarked or branded names, or what?

Well, to the best of my research, the answer is, they are “or what.”

People often incorrectly use the term acronym to describe anything made up of initial letters. But something like DNA (short for deoxyribonucleic acid) is rightly called an initialism. Because each letter is distinctly pronounced, this particular shorthand is not pronounced as “a word,” nor are words like GDP (Gross Domestic Product) FM (Frequency Modulation), VFW (Veterans of Foreign Wars) or TNT, IRS, or FBI for that matter.

The term acronym rightly describes anything made up of initial letters, but most dictionaries define them as “a word.” So, NATO (short for North Atlantic Trade Organization) is an acronym because it’s pronounced as “a word” just like scuba (self-contained underwater breathing apparatus), radar (radio detection and ranging), laser (light amplification by stimulated emission of radiation), and AWOL (Absent Without Official Leave). Even though each of these words is derived from only the initial letters of the terms they represent, they are not initialisms because they are pronounced as words in and of themselves and they are not abbreviations because they are not “shortened forms” of entire words. So words like TV or ICU or ER would not qualify as acronyms using this definition.

An abbreviation is a shorted form of any word such as Mr. for Mister or abbr. for abbreviations (or abbreviated). An abbreviation usually consists of the first few letters of any longer word such as Capt. for Captain or cent. for century. This is not always the case because an abbreviation can also consist of additional selected letters in the word other than the initial letters such as in Assn. for Association or Dept. for Department.

Words like T-shirt and A-frame which amount to a letter combined with a word don’t completely fall into any of these three categories. They are just specific letters (or sometimes numbers) used as words or word parts. If you figure out what the “technical” term for them is, please enlighten me.

So, You may wonder if it’s properly capitalized like t-shirt or T-shirt, or a-frame or A-frame because that capitalization might look kind of funny in the middle of a sentence.

Here’s the skinny.

The capitalized T-shirt is correct. It is called a T-shirt because the shape of the actual garment resembles that of a capital letter T, in the same way that an A-frame’s shape resembles a capital letter A. This is why, with a T-shirt for example, Webster says it can also “less commonly” be spelled as “tee shirt” but makes no allowance whatsoever for “t-shirt” with a lowercase t.

Think of I-beam instead of lowercase i-beam since a cross-section of the beam of steel it is named for resembles a capital serif font letter I from the side. Think of a Q-tips swab with the stick inserted into a roundish shaped bit of cotton instead of q-tips swab which would have all the cotton on one side of the swab more like a toothbrush or a flag. But another reason to capitalize Q-tips specifically is because it is a trademarked term just like Kleenex or Xerox.

If the shape of the letter is the key, it’s always best to use the proper case of the letter. This is unlike words like T-Bill, or e-mail, or iPhone in which case the shape of the letter is not the determining factor. In these cases, there are also simple rules. If the letter is treated as a proper noun, like a Treasury Bill, capitalize it. If the letter represents a common noun, like electronic mail, capitalization follows the rules for common nouns. If the letter is capitalized or lowercase according to the company’s branding like an iPhone, follow the company’s branding.

Musical notations are treated as proper nouns. Therefore, notations such as C-minor or B-major, are always capitalized regardless of where they fall in a sentence. Likewise capitalize the notes as they pertain to parts of musical instruments such as the A-string or the B flat key (as in on a keyboard, not as in “the key of B-flat”), although the parts of the musical instrument themselves (e.g., string, key) are not capitalized because they are not proper nouns.

Since this is often confusing, I searched dictionaries and the “interwebs” for all the examples and forms I could find. An alphabetical list of some words dependent upon letters written in their proper case follows:

1-A (aka 1A)—WWII through end of Draft era term designating someone as "Acceptable" for military service based on medical, dental, and other examinations.

1-AM (aka 1AM)-WWII through end of Draft era term designating someone as "Acceptable Medical" specialist available for military service.

1-AO (aka 1AO)-WWII through end of Draft era term designating someone as "Acceptable" Conscientious "Objector" opposed to training and military service requiring a combatant role or the use of deadly arms but able to fulfill service obligation in a noncombatant role within the military.

1-O (aka 1O)-WWII through end of Draft era term designating someone as a Conscientious "Objector" available for alternate community service outside the military.

2-by-4 (less commonly 2x4)--actually a misnomer, this is a beam or plank of wood that today actually measures 1.5 inches tall by 3.5 inches wide and is usually cut to varying even lengths with standard lengths being 8, 10, or 12 even feet. Once upon a time the raw cut untreated planks fresh from the sawmill cants actually measured 2 inches by 4 inches but modern treatments of drying, pressing, planing, etc., shave off a quarter inch here and there.

4-F (aka 4F)—WWII through end of Draft era term designating someone who "failed" to meet the minimum acceptable standards of the medical, dental, or other examination resulting in being rejected from entrance to military service due to being unfit for duty. Though often in error, it should not be reversed and written as "F-4" and probably only ever was due to confusion with the military fighter/bomber McDonnell Douglas F-4 Phantom that first appeared in the late 1950s.

4x4 (less commonly four-by-four)--a four-wheel automotive vehicle such as a pickup truck or Jeep equipped with four-wheel drive.

A-bomb—An atomic bomb.

A-key—or A sharp key, or A flat key, or any of the notes from "doe to ti" listed as A to G when speaking of a particular key on a keyboard.

A-levels—A set of exams given at about age 18 (British).

A-list—The group of people who are the most desirable for something.

A-major—or A-minor, or any of the notes from "doe to ti" listed as A to G followed by that notation. Likewise in the flat or sharp of the octaves.

A-string—traditionally, the third string on a violin. For almost 500 years, violins have generally had four strings tuned G, D, A, and E. Guitars and harps obviously can have many strings from doe to ti and in more than one octave listed as A to G. So this may also be written as referring to the G-string, D-string, E-string, etc.

A-team—properly, Special Forces Operational Detachment-Alpha (SFODA). Each SFODA specializes in an infiltration skill or a particular mission-set (e.g., Military Freefall, combat diving, mountain warfare, maritime operations, etc.). Unlike the popular 1980s TV show, an actual SFODA consists of 12 highly trained soldiers.

B-school—(Graduate-level) Business School

B-word—a common euphemism for a very ugly derogatory sexist slur.

C-4 (less commonly C-four)—stands for Composition IV which is a stable high explosive composed of various chemicals that make it moldable and plastic. First found common use in the Vietnam War and is the primary explosive in the US Military Claymore Mine.

C-note—Century note, aka a $100 bill (common between 1920s and 1960s, now a bit dated).

C-rations (aka C-rats)—WWII through Vietnam War-era military term for "canned" rations.

D-day—military term for "the day of the invasion". "D" is a variable that allows planners to talk about the schedule of operations without actually knowing which day invasion day will fall on. This is important because the actual invasion day is always secret and usually isn't determined until the last minute. So, for example, two days before the invasion is "D-day minus 2" or just "D-minus 2"; three days later is "D-day plus 3". The "D" just stands for "day". (The hour of the invasion is "H-hour", with "H" standing for "hour" [see below].) "D-Day" has come to be popularly known as the day that the Allied troops invaded Normandy, probably the most pivotal battle of WWII.

D-ring--an item of hardware, usually a tie-down metal ring shaped like the letter "D" used primarily as a lashing point.

e-mail—electronic mail is usually no longer capitalized unless it begins a sentence since words like this and "internet" are no longer treated as proper nouns but common nouns.

figure-8 (aka figure-eight aka Flemish bend knot)—knot used for joining two ropes or cables of roughly similar size. A loose figure-8 knot is tied in the end of one length. The second length is then threaded backwards parallel to the first length.

F-word—a common euphemism for a very ugly swear word.

G-string—(1) the first and thickest string on a violin. For almost 500 years, violins have generally had four strings tuned G, D, A, and E.

G-string—(2) Probably named "G" after the thickest string on a violin, this is a very small garment that perhaps does--perhaps does not--cover the genitals. It may also have derived the "G" from "genitals," though etymology is not clear.

H-bomb—a hydrogen bomb

H-harness—usually attaches to a thick belt but can attach to a back pack or ruck sack, used in military applications to attach gear to a soldier.
