One wearing confused tramp's sweater? (6)
I believe the answer is:
armpit
'sweater?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'one wearing confused tramp's' is the wordplay.
'one' becomes 'i' (Roman numeral).
'wearing' means one lot of letters goes inside another.
'confused' indicates anagramming the letters.
'tramp' with letters rearranged gives 'armpt'.
'i' placed within 'armpt' is 'ARMPIT'.
Can you help me to learn more?
(Other definitions for armpit that I've seen before include "Hairy hollow" , "part of the body" , "(In anatomy) the axilla" , "depression which is personal" , "evident given "hands up"!" .)
