Inattentive member briefly getting in touch (8)
I believe the answer is:
careless
'inattentive' is the definition.
('careless' is associated in meaning with 'inattentive')
'member briefly getting in touch' is the wordplay.
'member' becomes 'leg' (I've seen this before).
'briefly' means to remove the last letter.
'getting in' means one lot of letters goes inside another.
'touch' becomes 'caress' (caress is a kind of touch**).
'leg' with its last letter taken off is 'le'.
'le' put into 'caress' is 'CARELESS'.
(Other definitions for careless that I've seen before include "Unconcerned; casual" , "Inattentive to risk" , "Cavalier" , "Negligent - nonchalant" , "Not paying enough attention" .)
