Drop and try by pro (5)
I believe the answer is:
forgo
'drop' is the definition.
(thesaurus)
'try by pro' is the wordplay.
'try' becomes 'go' (go is a kind of try).
'by' says to put letters next to each other.
'pro' becomes 'for' (I've seen this before).
'go' put after 'for' is 'FORGO'.
'and' is the link.
(Other definitions for forgo that I've seen before include "Sacrifice" , "Go without (something)" , "pass up" , "Do without (something desirable)" , "Relinquish, give up" .)
