On the way home from Edinburgh last week I discussed the subject of unusual words with my friends. Words like 'queueing' which have 5 vowels in a row, or 'catchphrase' which contains 6 consecutive consonants.
I particularly like words that have repeated letters or dots (as in 'hijinks' or 'Fiji'). Such words include 'wallless' (having no walls) and headmistressship.
Some words seem not to fit what they describe - for example: the word 'long' is short, and the word 'short' is longer. Same for the words 'big' and 'small'.
