More than one friend accepts bait without finishing (6)
I believe the answer is:
plural
'more than' is the definition.
(I've seen this before)
'one friend accepts bait without finishing' is the wordplay.
'one friend' becomes 'pal' (pal is a kind of friend**).
'accepts' is an insertion indicator.
'bait' becomes 'lure' ('lure' can be a synonym of 'bait').
'without finishing' means to remove the last letter.
'lure' with its last letter taken away is 'lur'.
'pal' placed around 'lur' is 'PLURAL'.
(Other definitions for plural that I've seen before include "Several" , "rivers, for example" , "Numbering more than one" , "More than one, not singular" , "Words such as "sheep" and "deer" (but not "cat" and "dog") can be this" .)
