'former college student dons understood in various languages' is the definition.
I can't judge whether this definition defines the answer.

'former college student dons understood' is the wordplay.
'former college' becomes 'poly' (polytechnic).
'student' becomes 'l' (as in L-plates for learner drivers).
'dons' is an insertion indicator (don means to wear or put on).
'understood' becomes 'got' (getting is a kind of understanding).
'l' inserted within 'got' is 'glot'.
'poly'+'glot'='POLYGLOT'
