Obvious to take in one person for surgery? (7)
I believe the answer is:
patient
'person for surgery?' is the definition.
I can't tell whether this defines the answer.
'obvious to take in one' is the wordplay.
'obvious' becomes 'patent' (similar in meaning).
'to take in' means one lot of letters goes inside another.
'one' becomes 'i' (Roman numeral).
'patent' enclosing 'i' is 'PATIENT'.
Can you help me to learn more?
(Other definitions for patient that I've seen before include "Cool" , "One in hospital" , "One being treated" , "Long-suffering - person in hospital" , "Enduring trying circumstances with an even temper" .)
