Injured person’s left for time without adequate attention? (8)
I believe the answer is:
casually
'without adequate attention?' is the definition.
(casual can mean careless)
'injured person's left for time' is the wordplay.
I cannot quite understand how this works, but
'left' could be 'al' (I've seen this in other clues) and 'al' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for casually that I've seen before include "In an unconcerned manner" , "In an off-hand manner" , "In a relaxed manner" , "Nonchalantly" .)
