Able to bear 50 family members (4)
I believe the answer is:
clan
'able to bear' is the definition.
I can't judge whether this definition defines the answer.
'50 family members' is the wordplay.
'50' suggests halving the letters.
'family members' becomes 'clansmen' (I've seen this in another clue).
'clansmen' halved is 'CLAN'.
Can you help me to learn more?
(Other definitions for clan that I've seen before include "Group with a tartan?" , "One from Benghazi" , "Highland grouping" , "Kinship group" , "People related by blood and marriage" .)
