Scold angrily for relative speed (4)
I believe the answer is:
rate
This clue might be a double definition.
'scold angrily' is the first definition.
'rate' can be an answer for 'scold' (I've seen this in another clue). I am not sure about the 'angrily' bit.
'relative speed' is the second definition.
(I've seen this before)
'for' acts as a link.
Can you help me to learn more?
(Other definitions for rate that I've seen before include "Merit; speed" , "Assess; be worthy of" , "Fixed price or relative speed" , "Relative speed (of progress)" , "The number of times something happens in a given period" .)
