Physician and Frenchman throw dice (5)
I believe the answer is:
medic
'physician' is the definition.
(I've seen this before)
'frenchman throw dice' is the wordplay.
'frenchman' becomes 'M' (abbreviation for Monsieur - like 'Mr').
'throw' indicates anagramming the letters.
'dice' with letters rearranged gives 'edic'.
'm'+'edic'='MEDIC'
'and' acts as a link.
(Other definitions for medic that I've seen before include "What was Basutoland" , "He may offer treatment" , "Word for 'doctor'" , "Health worker" , "Eg, doctor" .)
