A prom, perhaps, with a certain blend of players (3-2)
I believe the answer is:
'a certain blend of players' is the definition.
I can't tell whether this definition defines the answer.
'a prom perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'aprom' is an anagram of 'PRO-AM'.
'with' acts as a link.
Can you help me to learn more?
