Health worker and Frenchman throwing dice (5)
I believe the answer is:
medic
'health worker' is the definition.
(I've seen this before)
'frenchman throwing dice' is the wordplay.
'frenchman' becomes 'm' (abbreviation for Monsieur - like 'Mr').
'throwing' indicates anagramming the letters (letters get thrown around).
'dice' is an anagram of 'edic'.
'm'+'edic'='MEDIC'
'and' is the link.
(Other definitions for medic that I've seen before include "Physician (informal)" , "Eg, doctor" , "What was Basutoland" , "Word for 'doctor'" , "Health worker" .)
