Hamburger's good, on reflection, for Yank (3)
I believe the answer is:
tug
'yank' is the definition.
(both can mean to pull sharply)
'hamburger's good on reflection' is the wordplay.
'hamburger's' becomes 'ut' (I am not sure about this - if you are sure you should believe this answer much more).
'good' becomes 'g' (abbreviation).
'on' is a charade indicator (letters next to each other).
'reflection' is a reversal indicator.
'ut' after 'g' is 'gut'.
'gut' backwards is 'TUG'.
'for' is the link.
Can you help me to learn more?
(Other definitions for tug that I've seen before include "gravitational force" , "Small boat for towing others" , "Pull like small boat" , "A sharp pull or a towing boat" , "Pull suddenly; boat" .)
