Twitch regularly with this? (3)
I believe the answer is:
tic
This clue could be a double definition.
'twitch' is the first definition.
(I know that tic is a type of twitch)
'regularly with this?' is the second definition.
The definition suggests a singular noun which matches the answer.
Can you help me to learn more?
(Other definitions for tic that I've seen before include "Muscular contraction" , "Twitch in anticipation" , "Nervous twitch" , "Minor muscle spasm" , "Nervous habit" .)
