Checked hound in its basket (6)
I believe the answer is:
curbed
'checked' is the definition.
(synonyms)
'hound in its basket' is the wordplay.
I cannot quite understand how this works, but
'hound' could be 'cur' (I've seen this in another clue) and 'cur' is found within the answer.
The remaining letters 'bed' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for curbed that I've seen before include "Restrained or inhibited" , "Put under restraint" , "Restrained, say horse with strap" , "Placed restrictions on" , "Controlled" .)
