Mad family a potential cause of embarrassment (6,4)
I believe the answer is:
banana skin
'cause of embarrassment' is the definition.
(I've seen this before)
'mad family a potential' is the wordplay.
I cannot really understand how this works, but
'mad' could be 'bananas' (I've seen this in another clue) and 'bananas' is located in the answer.
'family' could be 'kin' (synonyms) and 'kin' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for banana skin that I've seen before include "Something to slip up on" , "Potential source of slip-up" , "Something causing downfall (colloq.)" , "potential hazard" , "something to cause embarrassment" .)
