Settle for a short welcome (5)
I believe the answer is:
agree
'settle' is the definition.
(I've seen this before)
'a short welcome' is the wordplay.
'short' means to remove the last letter.
'welcome' becomes 'greet' (I've seen this before).
'greet' with its last letter removed is 'gree'.
'a'+'gree'='AGREE'
'for' acts as a link.
(Other definitions for agree that I've seen before include "Enjoy view in common" , "Concur, coincide" , "get on" , "Concur, acquiesce" , "Say yes to a suggestion" .)
