A sylvan sound could be the result (6)

I believe the answer is:

rustle

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

'a sylvan sound' is the definition.
'rustle' can be an answer for 'sound' (rustle is a kind of sound). I'm unsure of the 'a sylvan' bit.

'could be the result' is the wordplay.
'could be' indicates anagramming the letters.
'result' with letters rearranged gives 'RUSTLE'.

Can you help me to learn more?

(Other definitions for rustle that I've seen before include "Swish - steal cattle" , "take animals" , "Wind-in-leaves noise" , "Steal ((eg, cattle)" , "Low sound of rubbing" .)

I've seen this clue in The Irish News.
