Did dangerous things to astonish a fellow (7)
I believe the answer is:
stunted
'did dangerous things' is the definition.
The definition and answer can be both to do with social activities as well as being past participle verbs.
Maybe there's a link between them I don't understand?
'astonish a fellow' is the wordplay.
'astonish' becomes 'stun' (I've seen this in another clue).
'a fellow' becomes 'ted' (man's name).
'stun'+'ted'='STUNTED'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for stunted that I've seen before include "Dwarfed, limited" , "Undersized" , "Retarded in growth" .)
