Generous leftist and others in family (7)
I believe the answer is:
kindred
'family' is the definition.
(I've seen this before)
'generous leftist' is the wordplay.
'generous' becomes 'kind' (similar in meaning).
'leftist' becomes 'red' (red can informally mean communist).
'kind'+'red'='KINDRED'
'and others in' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for kindred that I've seen before include "Relatives" , "Related (people)" , "Related by blood or marriage" , "Affinity" , "These spirits have similar tastes" .)
