Sound that's not meandering, say (6)
I believe the answer is:
strait
'sound' is the definition.
(I know that sound can be written as strait)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for strait that I've seen before include "Narrow stretch of water for artist" , "Narrow - artist (anag)" , "Narrow or difficult" , "Difficulty - strict" , "Narrow passage joining two large areas of water" .)
