Dramatic possibility of palsy (5)

I believe the answer is:

plays

I'm a little stuck... Click here to teach me more about this clue!

'dramatic possibility of palsy' is the definition.
I can't tell whether this defines the answer.

'of palsy' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'palsy' anagrammed gives 'PLAYS'.

Can you help me to learn more?

(Other definitions for plays that I've seen before include "Dramatist's works" , "Dramas" , "Dramatic works" , "Frolics" , "Theatrical works" .)

I've seen this clue in the Evening Standard.
