Any time you play Scrabble against a serious competitive player you can expect them to offer up words such as xu, and [L’INK:2418|CAPTION:zo] with a surprising degree of confidence. These words may be seldom encountered outside the popular board game, but two-letter words are gold dust to Scrabble players. They allow them to form several words in a single turn and thus greatly increase their score. So keen Scrabble players will make an effort to learn all 124 of the two-letter words in the official Scrabble word list, regardless of whether they would ever use them in a normal conversation.
In fact, there is a rather obscure principle of English spelling that states that nouns, verbs, and adjectives should contain at least three letters. This explains why nouns such as ‘inn’ and ‘bee’ and verbs such as ‘buy’ have one letter more than might be thought strictly necessary. So the two-letter words that are used in everyday English tend to be ‘function words’ that do not name or describe things, but which exist to provide grammatical structure: words such as ‘to’, ‘in’, ‘so’, and ‘as’.
But these everyday words make up less than half of the two-letter words that are allowable in tournament Scrabble play. As well as these, you are allowed to use some informal shortened forms of words (such as ‘ad’, ‘op’, and ‘mo’) and exclamations (such as ‘hm’, ‘oi’, and ‘yo’) that you will probably be familiar with but might think would be inadmissible.
And beyond these, there are over fifty two-letter combinations that you would probably never imagine were words. Many of these are borrowings from other languages, which explains why they do not follow the rule that English nouns, verbs, and adjectives should have at least three letters. Here are a few of the more exotic and intriguing ones:
aa volcanic rock consisting of angular blocks of lava
ai the three-toed sloth
gu a type of violin used in Shetland
ka a spirit believed by ancient Egyptians to exist in a person or statue
ko a traditional digging tool used in New Zealand
li a Chinese measurement of distance
ti a woody East Asian plant
xu a monetary unit of Vietnam worth one-hundredth of a dong
zo a Tibetan breed of cattle
That is just a selection, of course. If you want to outsmart your friends and learn all 124 of these killer Scrabble words, the full list can be found in the books and tools on the dedicated Scrabble page of this website.
