Grabbed wildly at a boy (5)
I believe the answer is:
taken
'grabbed' is the definition.
The definition and answer can be both to do with contact as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'wildly at a boy' is the wordplay.
'wildly' indicates an anagram.
'a boy' becomes 'ken' ().
'at' anagrammed gives 'ta'.
'ta'+'ken'='TAKEN'
Can you help me to learn more?
(Other definitions for taken that I've seen before include "This is spoken for" , "Kidnapped" , "Captured" , "Transported" , "Seized" .)
