Full origin of erstwhile →Frequently asked questions
What is the difference between 'erstwhile' and 'former'?
They mean the same thing, but 'erstwhile' is markedly more literary and slightly old-fashioned, so it stands out in plain prose. 'Former' is the neutral everyday choice and is almost always safer in business or news writing.
Does 'erstwhile' mean 'esteemed' or 'longtime'?
No, and this is the commonest error. 'Erstwhile' means only 'former'; calling someone 'our erstwhile colleague' says they no longer work with you, not that you value them. If you mean 'respected' use 'esteemed', and if you mean 'of long standing' use 'longtime'.
Can 'erstwhile' be used after the noun?
Not naturally. As an adjective it goes before the noun ('his erstwhile rival'), and the adverbial use after a noun ('the hall, erstwhile a chapel') now reads as deliberately archaic.
