Army medic to employ a shrinking violet? (5)
I believe the answer is:
mouse
'a shrinking violet?' is the definition.
(thesaurus)
'army medic to employ' is the wordplay.
I cannot quite understand how this works, but
'medic' could be 'mo' (medical officer) and 'mo' is located in the answer.
'employ' could be 'use' (synonyms) and 'use' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for mouse that I've seen before include "computer operator" , "Small rodent - computer device" , "Small rodent and cursor controller" , "Quiet type" , "Small verminous rodent" .)
