Remove the end piece, in particular (6)
I believe the answer is:
detail
'particular' is the definition.
(I know that particular can be written as detail)
'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' is the 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" .)
