Derided and cut short after capital doubles? (6)
I believe the answer is:
mocked
'derided' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for mocked that I've seen before include "made fun of" , "Scorned" , "Taunted, derided" , "Imitated with derision" , "Derided, scoffed at" .)
