Slump from sudden movement grasping oxygen (6)
I believe the answer is:
lounge
'slump' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'sudden movement grasping oxygen' is the wordplay.
I cannot really understand how this works, but
'oxygen' could be 'o' (atomic symbol for oxygen) and 'o' is found within the answer.
'movement' could be 'lunge' (lunge is a kind of movement) and 'lunge' is present in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
'from' acts as a link.
Can you help me to learn more?
(Other definitions for lounge that I've seen before include "Loll - sitting room" , "Sit idly in comfortable room" , "Take it easy" , "Recline in a very relaxed manner" , "Relax in sitting room?" .)
