I began, stupidly, to hold love as something found in bed (7)
I believe the answer is:
begonia
'something found in bed' is the definition.
I can't judge whether this defines the answer.
'i began stupidly to hold love' is the wordplay.
'stupidly' indicates anagramming the letters (a stupid ordering of the letters).
'to hold' means one lot of letters goes inside another.
'love' becomes 'o' (love means zero in tennis).
'i'+'began'='ibegan'
'ibegan' is an anagram of 'begnia'.
'begnia' enclosing 'o' is 'BEGONIA'.
'as' is the link.
Can you help me to learn more?
(Other definitions for begonia that I've seen before include "Tropical plant" , "colourful flower" , "Herbaceous plant whose flowers have no petals" , "Common garden plant" , "bloomer" .)
