Remove garments from relative, including hot pants (8)
I believe the answer is:
unclothe
'remove garments from' is the definition.
I can't tell whether this defines the answer.
'relative including hot pants' is the wordplay.
'relative' becomes 'uncle' (uncle is a kind of relative).
'including' is an insertion indicator.
'pants' indicates anagramming the letters (UK informal term for 'nonsense' or 'rubbish').
'hot' is an anagram of 'oth'.
'uncle' placed around 'oth' is 'UNCLOTHE'.
Can you help me to learn more?
(Other definitions for unclothe that I've seen before include "shed" , "lay bare" , "Reveal" , "Strip (someone)" , "set garments aside" .)
