Reprimands favourite fellow travellers? (7)
I believe the answer is:
carpets
'reprimands' is the definition.
(carpet can mean to heavily criticise)
'favourite fellow travellers?' is the wordplay.
I cannot quite see how this works, but
'favourite' could be 'pet' (synonyms) and 'pet' is found in the answer.
The remaining letters 'cars' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for carpets that I've seen before include "Reprimands (informal)" , "Floor-coverings" .)
