Handyman has bit of dope and round belly (8)
I believe the answer is:
factotum
'handyman' is the definition.
(I've seen this in another clue)
'bit of dope and round belly' is the wordplay.
'bit of dope' becomes 'fact' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'and' says to put letters next to each other.
'round' becomes 'o' (round can mean a round object).
'belly' becomes 'tum' (I've seen this in another clue).
'fact'+'o'+'tum'='FACTOTUM'
'has' is the link.
Can you help me to learn more?
(Other definitions for factotum that I've seen before include "Person employed for all kinds of work" , "Jack of all Trades" , "Handyman" , "Someone employed for a variety of jobs" , "General servant" .)
