One may be so in order to listen (6)
I believe the answer is:
silent
'one may be so' is the definition.
I can't judge whether this defines the answer.
'order to listen' is the wordplay.
'order to' is an anagram indicator (a different order to the letters).
'listen' anagrammed gives 'SILENT'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for silent that I've seen before include "Enlist (anag) - mum" , "Mute" , "Wordless" , "Inaudible" , "A continent" .)
