Question

What is 'not unknown'
to Antonio?​

Answer 1

.'Tis not unknown to you, Antonio, How much I have disabled mine estate, By something showing a more swelling port 130 Than my faint means would grant continuance. Antonio, you know how I've been using up my wealth, living a more lavish life than I can afford.

Answer 2

Answer:

I think this is from Act 1 Scene 1 of Merchant of Venice written by William Shakespeare.

Answer:

Antonio has promised Bassanio that he will tell about lady whom he loves but he forgets that he had told.

As we know that Bassanio had told Antonio about Portia and he thinks that he have not told about her so Bassanio says that the lady i.e. Portia is not unknown to Antonio.
