Part of tribe returns some headgear (5)
I believe the answer is:
beret
'headgear' is the definition.
(beret is a kind of headgear)
'part of tribe returns some' is the wordplay.
'part of' indicates the answer is hidden within the clue.
'BERET' is hidden within 'tribe returns some'.
(Other definitions for beret that I've seen before include "Frenchman's flat hat" , "French-style cap" , "Soft flat hat" , "Part of kit" , "item of headwear" .)
