Some dictionaries have a word for doctor (5)
I believe the answer is:
medic
'for doctor' is the definition.
(doctor is a type of medic)
'some dictionaries have' is the wordplay.
'have' indicates a hidden word.
'MEDIC' is hidden in the letters of 'some dictionaries'.
'a word' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for medic that I've seen before include "Eg, doctor" , "He may offer treatment" , "What was Basutoland" , "Health worker" , "Physician (informal)" .)
