I start to scold, being furious (5)
I believe the answer is:
irate
'furious' is the definition.
(I know that furious can be written as irate)
'i start to scold being' is the wordplay.
'start' means to remove the last letter (I've seen 'starts' mean this).
'to scold' becomes 'rate' (I've seen this in another clue).
'being' becomes 'e' (I can't explain this - if you can you should believe this answer much more).
'rate' with its last letter removed is 'rat'.
'i'+'rat'+'e'='IRATE'
Can you help me to learn more?
(Other definitions for irate that I've seen before include "Aggrieved" , "Hacked off" , "become irritated" , "I tear away, being annoyed" , "Not happy" .)
