'feisty old woman's protest about limited hearing' is the definition.
I can't tell whether this definition defines the answer.

'protest about limited hearing' is the wordplay.
'protest' becomes 'march' (marching is a kind of protesting).
'about' means one lot of letters goes inside another.
'limited' means to remove the last letter.
'hearing' becomes 'trial' (I've seen this before).
'trial' with its last letter taken off is 'tria'.
'march' going around 'tria' is 'MATRIARCH'.
