I scold, being very cross (5)
I believe the answer is:
irate
'very cross' is the definition.
(I've seen this before)
'i scold' is the wordplay.
'scold' becomes 'rate' (I've seen this in another clue).
'i'+'rate'='IRATE'
'being' is the link.
(Other definitions for irate that I've seen before include "Aggrieved" , "Annoyed, exasperated" , "Wrathful" , "Narked" , "Wild" .)
