Curled up asleep beside the daughter, is happy (7)
I believe the answer is:
pleased
'curled up' is the definition.
Both the definition and answer are adjectives. Perhaps you can see a link between them that I don't see?
'asleep beside the daughter is happy' is the wordplay.
'beside' says to put letters next to each other (I've seen this in other clues).
'the daughter' becomes 'd' (genealogical abbreviation).
'is happy' indicates an anagram (happy can mean slightly drunk).
'asleep' after 'd' is 'dasleep'.
'dasleep' with letters rearranged gives 'PLEASED'.
Can you help me to learn more?
(Other definitions for pleased that I've seen before include "Gratified" , "Euphoric" , "Glad" , "Well satisfied" , "Grateful, delighted" .)
