Deep rough sound from Greek hunting bird (5)
I believe the answer is:
growl
'deep rough sound' is the definition.
'growl' can be an answer for 'sound' (I have seen 'gruff sound' mean 'growl' so perhaps 'sound' could also mean 'growl'). I'm not sure about the 'deep rough' bit.
'greek hunting bird' is the wordplay.
I cannot really understand how this works, but
'greek' could be 'gr' (abbreviation for Greek) and 'gr' is present in the answer.
'bird' could be 'owl' (owl is a kind of bird) and 'owl' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'from' is the link.
Can you help me to learn more?
(Other definitions for growl that I've seen before include "Hostile dog's noise" , "gruff sound" , "Snarl" , "Grumble; roar" , "Surly grumble" .)
