A weapon is brought back in her basket (5)
I believe the answer is:
'a weapon' is the definition.
(sabre is a kind of weapon)
'brought back in her basket' is the wordplay.
'brought back' says the letters should be written in reverse.
'in' says the answer is hidden in the clue.
'erbas' is hidden in the letters of 'her basket'.
'erbas' back-to-front is 'SABRE'.
'is' acts as a link.
(Other definitions for sabre that I've seen before include "Bares (anag.)" , "Walt --, cartoonist" , "weapon" , "Large wasp" , "Heavy cavalry sword" .)
