Took a good look at dodgy deals (6)
I believe the answer is:
stared
'took a good' is the definition.
The answer and definition can be both related to bodily activities as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
'look at dodgy deals' is the wordplay.
'look' becomes 'stare' (staring is a kind of looking).
'at' means one lot of letters go next to another.
'dodgy deals' becomes 'd' (I am not sure about this - if you are sure you should believe this answer much more).
'stare'+'d'='STARED'
Can you help me to learn more?
(Other definitions for stared that I've seen before include "Gaped" , "Looked at long and fixedly" , "Looked long and hard at" , "Gazed intently at" , "Looked with a fixed gaze" .)
