Such strings suit many a duet, somehow (5)
I believe the answer is:
muted
'such strings suit many a duet somehow' is the definition.
I can't tell whether this defines the answer.
'many a duet somehow' is the wordplay.
'many' becomes 'm' (Roman numeral for a thousand).
'somehow' indicates anagramming the letters.
'duet' with letters rearranged gives 'uted'.
'm'+'uted'='MUTED'
Can you help me to learn more?
(Other definitions for muted that I've seen before include "In a softened tone" , "Muffled or silent" , "fitted with silencer" , "Less than enthusiastic" , "Temporarily speechless" .)
