Sound found in Arabic language (5)
I believe the answer is:
clang
'sound' is the definition.
(clang is a kind of sound)
'in arabic language' is the wordplay.
'in' indicates the answer is hidden within the clue.
'CLANG' is hidden within 'arabic language'.
'found' acts as a link.
(Other definitions for clang that I've seen before include "Noise as of cymbals" , "Metallic ring" , "A loud ringing sound" , "Ring loud and deep" , "Resounding effect" .)
