Type of service that's subject to writing? (9)
I believe the answer is:
underhand
'type of service that's' is the definition.
I can't judge whether this defines the answer.
'subject to writing?' is the wordplay.
'subject to' becomes 'under' (being subject to a law is being under it).
'writing?' becomes 'hand' ('hand' can refer to someone's handwriting).
'under'+'hand'='UNDERHAND'
Can you help me to learn more?
(Other definitions for underhand that I've seen before include "done deviously through cover" , "Crafty" , "Reporting to worker" , "Deceptively" , "Surreptitiously, sounds like a lower employee" .)
