2276: nonce Mar 10, 2021

A number of modern words are the result of wrong division, i.e. splitting or affixing sounds across multiple words such as in 'napkin' or 'adder' which respectively gained and lost an [n] due to the indefinite article 'an'. This is not the only word for which it has happened though, as can be seen with 'nonce' meaning 'a single occasion' as in "it worked for the nonce". This is connected, unsurprisingly to 'once' but with wrong division from a Middle English word 'þan' (than) as in 'þan anes'. In fact, 'anes' in 'once' and 'nonce' is actually from the genitive form of 'one' (ān) as in "of one". Separately, 'nonce' is also British slang but it has nothing in relation to the other meaning. It couldn’t possibly have been from ‘an’ as with the other words mentioned above as is commonly expected in cases of wrong division, since that has the same root as the ‘one/once’ in ‘nonce’ itself.
