Hand of 6 bananas, about to split that (5)
I believe the answer is:
reach
'hand' is the definition.
('reach' can be a synonym of 'hand')
'6 bananas about to split that' is the wordplay.
I cannot quite see how this works, but
'about' could be 'rea' (I've seen this in other clues) and 'rea' is located in the answer.
The remaining letters 'ch' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Other definitions for reach that I've seen before include "Come up to - stretch between bends" , "compass" , "Attain - make contact with" , "Arrive at the destination" , "Hands up" .)
