wick: [OE] Wick ‘burning fibre in a candle or lamp’ has West Germanic relatives in German wieche and Dutch wiek, but its ultimate ancestry is uncertain (a connection has been suggested with Old Irish figim ‘I weave’). The wick of get on someone’s wick ‘annoy someone’, incidentally (first recorded in 1945), is probably a different word. It appears to be short for Hampton Wick, rhyming slang for ‘prick, penis’ (Hampton Wick is a district in southwest London; its wick means historically ‘village, town’, and is the same word ultimately as the -wich, -wick of English place-names).
