'Gift' for a grand seaman! (3)
I believe the answer is:
gab
'gift' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'a grand seaman' is the wordplay.
'a grand' becomes 'g' ('G' can be a synonym of 'grand').
'seaman' becomes 'ab'.
'g'+'ab'='GAB'
'for' is the link.
Can you help me to learn more?
(Other definitions for gab that I've seen before include "Loquacity the gift of it" , "This may be a gift" , "The gift of the - means verbal fluency" , "Talk, chatter (colloq.)" , "Natter" .)
