Pay attention to silent order (6)

I believe the answer is:

listen

'pay attention to' is the definition.
(thesaurus)

'silent order' is the wordplay.
'order' indicates anagramming the letters.
'silent' anagrammed gives 'LISTEN'.

(Other definitions for listen that I've seen before include "Lend an ear (6)" , "Give one's attention" , "Make an effort to hear" , "Take notice" , "Attend (to a sound)" .)

I've seen this clue in The Mirror.
