Told of being a family member (7)
I believe the answer is:
related
'told' is the definition.
(as in relating a story)
'being a family member' is the wordplay.
I cannot really see how this works, but
'being' could be 'ted' (Ted is an example) and 'ted' is present in the answer.
'a' is within the answer.
This may be the basis of the clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for related that I've seen before include "spilled the beans" , "of one family" , "As siblings obviously are" , "Connected, by kinship say" , "Connected by blood or marriage" .)
