Sound nervous delivering question on state (6)
I believe the answer is:
quaver
'sound' is the definition.
(I know that quaver is a type of sound)
'question on state' is the wordplay.
'question' becomes 'qu' (abbreviation).
'on' says to put letters next to each other (in a down clue, letters appear on others).
'state' becomes 'aver' (both can mean to declare).
'qu'+'aver'='QUAVER'
'nervous delivering' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for quaver that I've seen before include "Tremble; musical note" , "Half-crotchet" , "Tremble - half a crotchet" , ".Speak in a trembling voice" , "(Of voice) tremble" .)
