A piece of material sown into a garment by most of the group in Air Force? (6)
I believe the answer is:
gusset
'a piece of material sown into a garment by most of' is the definition.
I can't tell whether this defines the answer.
'group in air force?' is the wordplay.
'group' becomes 'se' (I can't explain this - if you can you should give a lot more credence to this answer).
'in' means one lot of letters goes inside another.
'air force?' becomes 'gust' (I've seen this in another clue).
'se' placed within 'gust' is 'GUSSET'.
'the' is the link.
Can you help me to learn more?
(Other definitions for gusset that I've seen before include "Strengthening insert in garment" , "Piece of material used to strengthen or enlarge a garment" , "Inset piece of fabric" , "Strengthening piece of fabric" , "Strengthening material insert" .)
