Look around you for light dressing (5)
I believe the answer is:
gauze
'light dressing' is the definition.
'gauze' can be an answer for 'dressing' (I have seen 'Medical dressing ' mean 'gauze' so perhaps 'dressing' could also mean 'gauze'). I'm not sure about the 'light' bit.
'look around you' is the wordplay.
'look' becomes 'gaze' (gazing is a kind of looking).
'around' means one lot of letters goes inside another.
'you' becomes 'u' (homophones).
'gaze' going around 'u' is 'GAUZE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for gauze that I've seen before include "Medical cloth" , "first-aid material" , "Surgical dressing of muslin" , "Thin bleached cotton cloth used for dressings etc" , "Thin, transparent fabric" .)
