BIONDELLO: Why, is it not news, to hear of Petruchio's coming?
BAPTISTA: Is he come?
BIONDELLO: Why, no, sir.
BAPTISTA: What then?
BIONDELLO: He is coming.
BAPTISTA: When will he be here?
BIONDELLO: When he stands where I am and sees you there.
An extract from Taming of the Shrew Act 3 Scene 2
What does 'come' mean in this context? I guess that come could be substituted for here. But after searching for what come could have a second meaning in middle english, I came up with nothing. Does anyone have sufficient evidence to be able to prove that my claim is correct or disprove it and come up with an alternate solution?
Edit to clarify why my question is different from this. It is because I am interested in the word 'come' and not 'become.' The other answer does not satisfy my queries which is the evidence. I believe that these two topics are completely different and under no circumstances is my question a duplicate.
