Rough schedule announced (6)
I believe the answer is:
coarse
'rough' is the definition.
(associated in meaning)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for coarse that I've seen before include "Large-grained or rough to the touch" , "Rude, vulgar" , "Inferior" , "Rough, uncouth" , "Rough in texture, or vulgar" .)
