Looking embarrassed by joke about new family (7)
I believe the answer is:
kindred
'new family' is the definition.
'kindred' can be an answer for 'family' (thesaurus). I'm not certain of the 'new' bit.
'looking embarrassed by joke' is the wordplay.
'looking embarrassed' becomes 'red' (I've seen this before).
'by' means one lot of letters go next to another.
'joke' becomes 'kind' (I can't justify this - if you can you should give a lot more credence to this answer).
'red' put after 'kind' is 'KINDRED'.
'about' is the link.
Can you help me to learn more?
(Other definitions for kindred that I've seen before include "Relatively" , "Associated - relations" , "Related; similar in kind" , "Related by blood - having similar qualities" , "Family and relations" .)
