Live temporarily with American in hovel (4)
I believe the answer is:
stay
'live temporarily' is the definition.
'stay' can be an answer for 'live' (thesaurus). I am not certain of the 'temporarily' bit.
'american in hovel' is the wordplay.
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'in' indicates putting letters inside.
'hovel' becomes 'sty' (I've seen this in another clue).
'a' inserted into 'sty' is 'STAY'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for stay that I've seen before include "Support, delay" , "guy giving > support" , "guy to > put off" , "Stanchion" , "Remain; brace" .)
