Drink with a twitch that's theatrical (8)
I believe the answer is:
dramatic
'theatrical' is the definition.
(I've seen this in another clue)
'drink with a twitch' is the wordplay.
'drink with' becomes 'dram' (small alcoholic drink. I am not sure about the 'with' bit.).
'twitch' becomes 'tic' (tic is a kind of twitch).
'dram'+'a'+'tic'='DRAMATIC'
'that's' is the link.
Can you help me to learn more?
(Other definitions for dramatic that I've seen before include "Sudden and striking" , "Sensational, thrilling" , "Thrilling in effect" , "relating to plays, etc" , "Histrionic" .)
