Offhand and breezy (4)
I believe the answer is:
airy
I believe this clue is a double definition.
'offhand' is the first definition.
(I've seen this before)
'breezy' is the second definition.
(I've seen this before)
'and' is the link.
(Other definitions for airy that I've seen before include "Well ventilated; nonchalant" , "Spacious; delicate" , "Delicate; dismissive" , "Old astronomer" , "Flippant" .)
