Elizabeth and Bill behind post and fences at The Foundation leading to leaves on the pond (4,4)
I believe the answer is:
lily pads
'leaves on the pond' is the definition.
'lily pads' can be an answer for 'leaves' (lily pad is a kind of leaf). I am not sure about the 'on the pond' bit.
'elizabeth and bill behind post and fences at the foundation' is the wordplay.
I cannot really understand how this works, but
'bill' could be 'ad' (advertisement stuck on wall) and 'ad' is found in the answer.
'post' could be 'p' (abbreviation as in PS for postscript) and 'p' is found in the answer.
This explanation may well be incorrect...
'leading to' acts as a link.
Can you help me to learn more?
(Another definition for lily pads that I've seen is " Floating leaves of a water plant".)
