Great pleasure of daughter leading rowing crew across lake (7)
I believe the answer is:
delight
'great pleasure' is the definition.
(I've seen this before)
'daughter leading rowing crew across lake' is the wordplay.
'leading' indicates taking the first letters.
'rowing crew' becomes 'eight' (I've seen this before).
'across' means one lot of letters goes inside another.
'lake' becomes 'l'.
The first letter of 'daughter' is 'd'.
'eight' enclosing 'l' is 'elight'.
'd'+'elight'='DELIGHT'
'of' acts as a link.
(Other definitions for delight that I've seen before include "charm" , "entrance?" , "Gladden" , "Enchant" , "Give great pleasure to" .)
