Often, he brings bag over with a present, to start with, and has a great way with words (4,2,3,3)
I believe the answer is:
gift of the gab
'words' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'often he brings bag over with a present to start with and has a great way' is the wordplay.
I cannot really see how this works, but
'often' could be 'oft' (synonyms) and 'oft' is found in the answer.
'he' could be 'ab' and 'ab' is located in the answer.
'present' could be 'gift' (synonyms) and 'gift' is found in the answer.
'great' could be 'g' (abbreviation in place names) and 'g' is present in the answer.
'way' could be 'e' (Compass direction - East) and 'e' is found in the answer.
A single letter 'h' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'with' is the link.
Can you help me to learn more?
(Other definitions for gift of the gab that I've seen before include "Ability to talk well" , "Ability to speak fluently, often wittily" , "Ability to speak effortlessly" , "Ability to speak well" , "Ability to speak persuasively" .)
