Some clear sounds — heard by these? (4)
I believe the answer is:
ears
'these?' is the definition.
The definition suggests an adverb but the answer is not.
'some clear sounds heard' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'EARS' is hidden within 'clear sounds heard'.
'by' acts as a link.
Can you help me to learn more?
(Other definitions for ears that I've seen before include "Listening organs" , "Auditory organs" , "Auditors" , "''He who has ... to hear, let him hear'' (bible)" , "Auricles" .)
