Fitting carpets, disposing of odd bits (3)

I believe the answer is:

apt

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

'fitting' is the definition.
(both mean appropriate)

I don't understand the rest of the clue.

(Other definitions for apt that I've seen before include "Ready to learn" , "Apposite, appropriate" , "clever" , "Prone" , "may be appropriate" .)

I've seen this clue in The Times.
