Coarse, cloth-headed, uncivil! (5)

I believe the answer is:

crude

I'm a little stuck... Click here to teach me more about this clue!

'coarse' is the definition.
(synonyms)

'cloth-headed uncivil' is the wordplay.
'cloth-headed' becomes 'c' (this might be a standard abbreviation I've not previously seen).
'uncivil' becomes 'rude' (synonyms).
'c'+'rude'='CRUDE'

Can you help me to learn more?

(Other definitions for crude that I've seen before include "Petroleum" , "Raw, unrefined" , "Raw, immature" , "foul-mouthed?" , "Natural mineral oil" .)

I've seen this clue in the Evening Standard.
