Ted's upset about Al being struck (5)
I believe the answer is:
dealt
'struck' is the definition.
The answer and definition can be both to do with ownership as well as being past participle verbs.
Maybe there's an association between them I don't understand?
'ted's upset about al' is the wordplay.
'upset' shows that the letters should be reversed in order.
'about' means one lot of letters goes inside another.
'ted' in reverse letter order is 'det'.
'det' enclosing 'al' is 'DEALT'.
'being' acts as a link.
Can you help me to learn more?
(Other definitions for dealt that I've seen before include "Gave out playing cards" , "Delta (anag.)" , "Dispensed (cards)" , "Distributed playing cards" , "Traded" .)
