Belonging to the same family as a monarch almost (4)
I believe the answer is:
akin
'belonging to the same' is the definition.
I can't judge whether this defines the answer.
'family as a monarch almost' is the wordplay.
I cannot really understand how this works, but
'family' could be 'kin' (synonyms) and 'kin' is found within the answer.
'a' is within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for akin that I've seen before include "Seemingly related" , "Having similar characteristics" , "Related by blood" , "not totally similar" , "Similar in quality" .)
