Cause of unexpected fall perhaps in British people eating pineapple (6,4)
I believe the answer is:
banana skin
'cause of unexpected fall perhaps' is the definition.
I know nothing about this answer so I can't tell whether this works.
'british people eating pineapple' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'people' becomes 'kin' (I've seen this in other clues).
'eating' indicates putting letters inside.
'pineapple' becomes 'ananas' (synonyms).
'b'+'kin'='bkin'
'bkin' going around 'ananas' is 'BANANA SKIN'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for banana skin that I've seen before include "slipper" , "Potential disaster" , "Potential downfall" , "Something unforeseen that may cause a slip-up" , "pedestrian problem" .)
