Hot-headed, breezy and hirsute (5)
I believe the answer is:
hairy
'hirsute' is the definition.
(I know that hirsute can be written as hairy)
'hot-headed breezy' is the wordplay.
'hot-headed' becomes 'h' (this could be a standard abbreviation I've not previously seen).
'breezy' becomes 'airy' (I've seen this before).
'h'+'airy'='HAIRY'
'and' is the link.
Can you help me to learn more?
(Other definitions for hairy that I've seen before include "triggering alarm" , "With locks" , "Hirsute - dangerous" , "fraught with danger" , "Having had a close shave? Not so" .)
