Fed sister with fruit following flood (8)
I believe the answer is:
inundate
'flood' is the definition.
(I know that flood can be written as inundate)
'fed sister with fruit' is the wordplay.
'fed' becomes 'i' (I can't explain this - if you can you should give a lot more credence to this answer).
'sister' becomes 'nun' (sister is a term of address for a nun).
'with' means one lot of letters go next to another.
'fruit' becomes 'date' (date is a kind of fruit).
'i'+'nun'+'date'='INUNDATE'
'following' acts as a link.
Can you help me to learn more?
(Other definitions for inundate that I've seen before include "Overrun" , "Flood (a place)" , "Submerge or cover in water" , "Flood - and unite (anag)" , "'Flood, swamp (8)'" .)
