The first chap gets a toy (5)
I believe the answer is:
teddy
'a toy' is the definition.
(teddy is a kind of toy)
'the first chap' is the wordplay.
'the first' becomes 't' (est letter of 'the').
'chap' becomes 'eddy' ().
't'+'eddy'='TEDDY'
'gets' is the link.
(Other definitions for teddy that I've seen before include "Type of bear" , "A child's toy bear" , "plaything" , "Cuddly toy" , "Child's soft toy" .)
