Suddenly throw jack, queen and king (4)
I believe the answer is:
jerk
'suddenly throw' is the definition.
'jerk' can be an answer for 'throw' (thesaurus). I am not certain of the 'suddenly' bit.
'jack queen and king' is the wordplay.
'jack' becomes 'J' (playing card abbreviation).
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'and' says to put letters next to each other.
'king' becomes 'K' (abbreviation for king in chess).
'j'+'er'+'k'='JERK'
Can you help me to learn more?
(Other definitions for jerk that I've seen before include "preserved beef" , "Yank, idiot" , "Jolt; tug" , "Tug suddenly" , "Twitch" .)
