Does this sound a note of familiarity? (4)
I believe the answer is:
bell
'does this sound a note of familiarity?' is the definition.
'bell' can be an answer for 'sound' (bell is a kind of sound). I am not certain of the rest of the definition.
'sound a note of familiarity?' is the wordplay.
'sound' shows a homophone (sound like).
'a note' becomes 'b' (musical note).
'of familiarity?' becomes 'll' (I am not sure about this - if you are sure you should believe this answer much more).
'b' is a homophone of 'be'.
'be'+'ll'='BELL'
Can you help me to learn more?
(Other definitions for bell that I've seen before include "Buzz" , "Telephone call?" , "Ringing device" , "It makes a ringing sound when hit with a clapper" , "Something to jingle?" .)
