Bound half of peas held by stick (5)
I believe the answer is:
roped
'bound' is the definition.
(roping is a kind of binding)
'half of peas held by stick' is the wordplay.
'half of' indicates taking half.
'held by' is an insertion indicator.
'stick' becomes 'rod' (I've seen this before).
'peas' with half the letters taken is 'pe'.
'pe' inserted into 'rod' is 'ROPED'.
(Other definitions for roped that I've seen before include "held by painter" , "(Of climbers) connected together by line" , "Lassoed" .)
