Bone carried by tribesman (3)
I believe the answer is:
rib
'bone' is the definition.
(rib is a type of bone)
'carried by tribesman' is the wordplay.
'carried by' says the answer is hidden in the clue.
'RIB' is hidden in the letters of 'tribesman'.
(Other definitions for rib that I've seen before include "Thin bone" , "Curved bone joined to the spine" , "Eve was known as Adam's ..." , "Eve is knownj as Adam's . . ." , "Bone; supporting member" .)
