Little kids grabbing tail of tree bears (5)
I believe the answer is:
totes
'bears' is the definition.
(I've seen this before)
'little kids grabbing tail of tree' is the wordplay.
'little kids' becomes 'tots' (I've seen this in another clue).
'grabbing' is an insertion indicator.
'tail of' suggests the final letters.
The last letter of 'tree' is 'e'.
'tots' enclosing 'e' is 'TOTES'.
(Other definitions for totes that I've seen before include "Carries or shoulders" , "Bears" , "Carries, lugs" , "Carries the betting system" , "Carries, drags" .)
