A few months ago in the Lounge we took a tour through the Visual Thesaurus based on the number seven. We thank the subscribers who pointed out Facts Previously Unknown to us, concerning two other languages in which the words for seven and week were etymologically related - i.e., Italian and Romanian. This month, we are taking a somewhat more specialized look at three. It's a number of nearly mystical powers, as a brief look at its wordmap suggests: even without considering its many appearances in other words, the words denoting a group of three (trio, troika, triplet, threesome, tercet, triad, etc.) suggest that it is a number with a mission.

Our specific interest in three, for which the VT will provide a few object lessons, stems from an observation made by the Danish linguist Otto Jespersen. It has come to be known as the "three letter rule" and it goes thus: content words in English (as distinct from function words) must have three or more letters. To put it another way, English is happy to spell function words (prepositions, pronouns, articles, conjunctions, exclamations and the like) with one or two letters, but words with meaning that is largely independent of context (that is, nouns, verbs, adjectives, and adverbs) cannot slip by with only one or two symbols to represent them in writing.

The corollary of this rule is that content words with pronunciations identical to function words are distinguished from them in writing by the addition of a (superfluous) consonant. To put it another way, and in the words of an author we'll mention in the links below, "a spoken content word that would logically correspond to two letters is 'padded out' with an extra consonant to avoid confusion with two-letter function words." To illustrate, all of the following content words are homophones of function words that are spelled with one or two letters in English: aye, bee, bye, inn, know, oar, sew, two, wee, and for some speakers, dew.

If you're like us, the first thing you think when you hear a new rule is whether or not there are exceptions, and in the case of language, the answer is nearly always yes. But over many centuries, English has settled down in its orthography remarkably well, such that the exceptions are few, and they tend to confirm the general application of the three letter rule.

At first blush, the commonest exceptions to the three letter rule are the verbs go and do. A look at their wordmaps (and you may want to don your eyeshades or turn off the other parts of speech before you look) reveal that these words are both true workhorses in English. In fact, you could almost argue that they have little meaning independent of context since they are both so polysemous. Dictionaries inform us that both do and go were not always spelled with two letters - they weighed in with three in both Middle English and Old English - and interestingly, all of their inflections are spelled with three or more letters. Along with being a denotative verb, do is also a function word in English, being required to form some tenses and various negations and questions.

Three other wee content fellows that come rushing to mind are ox, ax, and ex. There are all genuine exceptions to the three letter rule, though they exhibit a common pattern: a logical writing system (which English lacks to some degree) would spell them with three (or more) letters, since they each contain three phonemes: along the lines, for example, of German ochs, the ancestor of ox. It is only by virtue of x's habit of representing two phonemes (/ks/) that these words squeak by with two letters. Ax, by the way, is a spelling approved only in American English; the Brits spell it axe. Ex has become acceptable shorthand for one's former spouse or squeeze presumably because of the frequency with which these individuals appear in the modern world. (We note, however, that this usage dates back to the earlier part of the 19th century, which from this vantage doesn't seem all that modern!)

Other exceptions to the three letter rule are less compelling and tend to confirm the rule, because in the back of our minds we're thinking: these things denote rather ephemeral and airy entities anyway, and so perhaps don't deserve the full three-letter monty of a genuine content word. There are, for example, the syllables of the solfa scale, six of which are spelled with two letters (do, re, mi, fa, la, and ti). There is our mathematical friend pi, usefully displayed to many decimal places in the VT, and along with it, the names of a few other Greek letters (mu, nu, xi). Another example is id, which has probably squeaked into English with only two letters because of the direct borrowing from Latin, and from the fact that despite everyone's allegedly having one, no one has ever actually seen one. The printers' measures en and em also fit the general pattern of wee, abstract things that hardly merit additional letters. In the typography trade, these have longer nicknames anyway (nut and mut or mutton) since their pronunciations are so similar. Finally, we should not neglect el: anyone who has stood under one in Chicago would not say it was ephemeral and airy at all! But then it is only an abbreviation for elevated railway.

Evidence of the three letter rule among denotative words is plentiful. A cartload of words in English consist of two phonemes only - a vowel and a consonant, or in some cases a diphthong and a consonant - yet these are spelled with three or more letters, of which one, usually a consonant, is often phonetically superfluous. Examples include add, ebb, egg, odd, and err. A few other two-phoneme content words are spelled with three (or more) letters because English lacks a single symbol for their consonant sound, such as ash. The settled convention of indicating a long vowel by using two vowels to spell it or by suffixing a silent e at the end of a word accounts for a whole slew of three (or more) letter English concoctions which represent only two phonemes: take, for example, ache, eke, oak, ace, and ice.

Many of the quirks, methods, and peculiar logic of the way English is written can be studied in The English Writing System by Vivian Cook: he is the author of the quote we used above. His book is published by Oxford University Press:

Vivian Cook also has a website with several curiosities of interest to explorers of English:

A theory we're tossing around in the Lounge at the moment is that nicknames in English exhibit a kinship in spirit with the three letter rule: English speakers like to reduce a full given name, regardless of length or complexity, to two or three phonemes whenever possible. When nicknames consist of two syllables, we also note, the final syllable is nearly always long e, though variously spelled. We haven't actually done the math, but here's a fairly complete list of name-to-nickname correspondences:

It's easy to argue that the main reason there are so few two-letter words is that there is an extremely limited number of combinations available. And that number is further limited by the fact that the words would predominantly be constructed from one vowel and one consonant (Aa being an obvious exception; but it is in Hawaiian).

It is attractive to consider, however, that linguistic efficiency could be improved with more two-letter words in the same manner that Morse Code was made more efficient by using shorter dash-dot groups for more common letters (dit for 'e', dit-dah for 'a', dah for 't' etc.).

My personal prediction, based upon hearing how teens and young adults speak, is that in 50 or 100 years there will only be two verbs: do and go. (Let's do lunch, I'll do her next, He goes, "hi.") Lack of vocabulary? Probably, resulting from inedequate education in the public schools. This opinion of mine derives mostly from frustration disguised as humor.

As pertains to the "fairly complete list of name-to-nickname correspondences," how about Max for Maxwell. That seems to fit the "bill." ("bill" may be an example too, but Max for Maxwell.)

Ah Nicknames!
I like the emerging hypothesis, and hate to rain on the parade, but perhaps you should expand your research to include our Antipodaen Cousins, especially the Aussies. They will take a forename, shorten it and add "o" - e.g. William =>Bill =>Billo.

Just to be contrary (what is it with Pesky Colonists? First it's tea in the harbour, then it's corruption of the language) the Aussies will add "ie" to people's surnames as a mark, I think, of affection - as in Shane Warne (he of the cricketing prowess)becomes Warnie.

Q. Why did the Pesky Colonists in America develop different linguistic quirks from their close relations in Australia. The bizzo about Aussies all being descended from convicts doesn't wash: Firstly, it's only partly true; and secondly, it ignores the reasons for most of the original colonists going to the Americas; here I am thinking of the Virginia colony, not the Johnny-Come-Latelies in New England.

I wonder if there is any group that I have not offended by this sort of 'Blazing Saddles' of an offering?

Regards

We tend to shorten most 'things'. In addition we add 'o' 'y' or 'a' to most names. ie.Chriso, Chrisy, Wacka.That is unless we have rr in the middle of a name which turns to zz. Garry becomes Gazza. Warren becomes Wazza and Barry becomes Bazza. I once met a fellow called Barry Buzza.Say it quickly.
It's the Ozzie/Aussie/Oz way.

Can you comment on the origin of nut and mut in this context? These represent interesting jargon.
Thanks,

I do have a comment, but it's not about the content as much as the structure of what I just read. The grammatical structure and the fabulous words simply thrilled me! Polysemous! Wow. A completely new word that I promptly looked up in the VT. Thank you for that.

In a world that's full of articles to read, I find I have little time to read material that both challenges and educates me. This particular article did just that; what a joy it was, too!

I concur with Susan. And the VT is so much easier than looking in the dictionary! I often wonder if there are others who keep dictionaries in every room of the house? I simply cannot advance a single word in reading when I come across a word that I do not know- I must be enlightened at once! Whether it is thirst for knowledge or just OCD, it is imperative nontheless. Thanks for sending intriguing stuff. And now I must absquatulate...

Thank you for this fascinating article. However, I believe you've mistakenly suggested that Vivian Cook is a woman. Vivian is a "he," not a "she."

A lovely article, but I wonder if "commonest" is really correct. Shouldn't it be "most common", or is that just "us Brits" that write that way?

Picking up on Dorothy Smith's theme, I think she's is underestimating the youth of today. I believe sentence structures will become very complex, such as "I'm going to go and do lunch". Of course, for emphasis the work "like" will be included quite randomly within every sentence.

At least three new friends - geographically unrelated - called me "Mare" in a informal, even intimate, manner. I guess some people have to shorten even unshortenable names. I liked it each time.

absquatulate! What a wonder of a word! I loved it immediately. And to further comment on comments.... I always spell A-X-E. It just seems more finished. Same with colour and flavour. When folks ask why I feel the need to "Brit-up" my spellings, I reply: it is simply more "recherche," thus confusing the hell out of them and setting them to wonder why I might wish to "frenchify" my speech!

Related to the the number seven and the word "week", Italian and Romanian are not the only languages in which there is etymologically relation. In Farsi (the language of Iranians), not only these two are etymologically related, they are literally related as well. The word for the number seven is "Haft" and the word for week is "Hafteh".

The VT IS more fun than a dictionary but doesn't replace the little goodies like, historic roots, variations according to specific languages, diacretics, et cetra. But it's still more fun and one can always subsribe the "Oxford" if they have a ravenous etymylogical appetite.
