What do these following lines mean?

Question

What are their meanings? from Romeo and Juliet Act 1 Scene 1 speech by the prince

" old Free-town"

" our common judgment-place"

"Canker'd with peace"

Answer 1

'I don't think you'll get any definitive answers regarding "Freetown". "Villa Franca" is mentioned in some source or other - one of Capulet's properties. Our "common judgment place" may be alluding to Verona's republican roots. It may be that the Prince is trying to get the feuding families to participate in a peace rather than just imposing a judgment (which he does anyway).'

'Old men must take their swords ("partisans") rusted with disuse ("cankered with peace"), to try to bring about peace ("to part your cankered hate").'

Hope this helps.
