Remove the end piece, in particular (6)
I believe the answer is:
detail
'particular' is the definition.
(synonyms)
'remove the end piece' is the wordplay.
'remove' becomes 'de' (I've seen this in other clues).
'the end piece' becomes 'tail' (tail is a kind of piece. I am not sure about the 'end' bit.).
'de'+'tail'='DETAIL'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for detail that I've seen before include "Factor" , "small military outfit" , "Troop detachment; small feature" , "A small part of something" , "Small or important part" .)
