Trees may be in this meadow at Flamborough Head (4)
I believe the answer is:
leaf
'trees may be in this' is the definition.
The definition suggests a singular noun which matches the answer.
'meadow at flamborough head' is the wordplay.
'meadow' becomes 'lea' (I've seen this before).
'at' is a charade indicator (letters next to each other).
'head' says to take the initial letters.
The first letter of 'flamborough' is 'f'.
'lea'+'f'='LEAF'
Can you help me to learn more?
(Other definitions for leaf that I've seen before include "See 1" , "Page or piece of foliage" , "Thin sheet of metal" , "Page; piece of tree" , "Sheet of written material" .)
