Make lonely Conservative law lord date nurses (7)
I believe the answer is:
seclude
'make lonely' is the definition.
I can't tell whether this defines the answer.
'conservative law lord date nurses' is the wordplay.
'conservative' becomes 'C' (UK political abbreviation).
'law lord' becomes 'lud' (term used in law as in m'lud, my lord).
'date' becomes 'see' (synonyms).
'nurses' is an insertion indicator (nurse can mean to hold onto or harbour).
'c'+'lud'='clud'
'clud' placed inside 'see' is 'SECLUDE'.
Can you help me to learn more?
(Other definitions for seclude that I've seen before include "Shut off" , "Keep (someone) away from other people" .)
