Clothing torn when keeping goal (7)
I believe the answer is:
raiment
'clothing' is the definition.
(I know that raiment is a type of clothing)
'torn when keeping goal' is the wordplay.
'torn when' becomes 'rent' (synonyms. I am not sure about the 'when' bit.).
'keeping' is an insertion indicator (some letters kept inside).
'goal' becomes 'aim' (aim is a kind of goal).
'rent' going around 'aim' is 'RAIMENT'.
Can you help me to learn more?
(Other definitions for raiment that I've seen before include "Clothing (literary)" , "Apparel" , "Something put on" , "dress?" , "clothing for poets" .)
