Showed great enthusiasm for a plot by a gang (6)
I believe the answer is:
mobbed
'showed great enthusiasm' is the definition.
The answer and definition can be both to do with motion as well as being past participle verbs.
Perhaps you can see a link between them that I can't see?
'a plot by a gang' is the wordplay.
'a plot' becomes 'bed' (bed is a kind of plot).
'by' says to put letters next to each other.
'a gang' becomes 'mob' ('mob' can be a synonym of 'gang').
'bed' after 'mob' is 'MOBBED'.
'for' is the link.
Can you help me to learn more?
(Other definitions for mobbed that I've seen before include "Crowded round (someone) in disorderly manner" , "Set upon by angry crowd" , "Surrounded in acclaim" , "Oppressed by crowd" , "Attacked by angry or enthusiastic crowd" .)
