Worker has a lot of bananas (4)
I believe the answer is:
hand
'bananas' is the definition.
(I've seen this before)
'worker has a lot' is the wordplay.
'worker' becomes 'han' (I can't justify this - if you can you should give a lot more credence to this answer).
'has' says to put letters next to each other.
'a lot' becomes 'd'.
'han'+'d'='HAND'
'of' is the link.
Can you help me to learn more?
(Other definitions for hand that I've seen before include "Crew member" , "Worker; pointer" , "audience response?" , "writing" , "Clock-pointer" .)
