Yearn to hold you at last with energy, then laze around (6)
I believe the answer is:
lounge
'laze around' is the definition.
'lounge' can be an answer for 'laze' (thesaurus). I'm not sure about the 'around' bit.
'yearn to hold you at last with energy' is the wordplay.
'yearn' becomes 'long-' (synonyms).
'to hold' means one lot of letters goes inside another.
'at last' says to take the final letters.
'with' is a charade indicator (letters next to each other).
'energy' becomes 'e' (physics symbol as in E=mc2).
The final letter of 'you' is 'u'.
'long' placed around 'u' is 'loung'.
'loung'+'e'='LOUNGE'
'then' acts as a link.
Can you help me to learn more?
(Other definitions for lounge that I've seen before include "Recline in a very relaxed manner" , "Stand about idly - in posh bar?" , "Comfortable room - relax in it" , "Room for relaxing" , "Sprawl" .)
