I have two new posts up at Macmillan Dictionary Blog. The wacky world of ‘wack’ and ‘whack’ looks briefly at these similar (and sometimes overlapping) words with many meanings in informal usage:
Whack meaning ‘hit’, as a noun and verb, is centuries old but remains informal compared to such synonyms as strike, blow, and knock. It may be onomatopoeic in origin, which is why it’s used as a sound effect in comic books and the old Batman TV show. It also has the related meaning ‘kill’, for example in criminal slang.
Wack emerged more recently as a back-formation from wacky. Initially it was a noun used to refer to a crazy or eccentric person – He’s a real wack – with wacko and whacko emerging as slangy offshoots. This was followed by adjectival wack meaning bad, unfashionable, stupid or of low quality, as in the anti-drugs slogan Crack is wack.
I go on to describe some of the ways the two words are used, and the possible limits of their interchangeability.
Enthusing about freedom of usage considers (and defends) the much-maligned back-formation enthuse:
Lots of words and usages are criticised or considered ‘incorrect’ when really they’re just colloquial, relatively new, or unsuited to formal use. As Michael Rundell wrote recently, ‘what might be inappropriate in a very formal setting may be perfectly acceptable in a conversation between friends’. . . .
What one generation finds ignorant or ridiculous, the next might adopt without fuss. Enthuse retains a semblance of impropriety, and is still frowned on by conservative writers and readers. Others, myself included, may have nothing against it but prefer periphrastic alternatives like ‘show enthusiasm’ or ‘be enthusiastic’.
The post details some of the criticism and commentary enthuse has received, and summarises its status in different varieties of English.
