"È pronta a iniziare?"

Translation: Is she ready to start?

Why can't this mean 'Is it ready to start'?

[mukkapazza]

It does now ;) but keep in mind a sentence like this would generally refer to a female

[Koolkaren]

Thanks! :)

Why not 'he' is ready to start?

[Donna_Diana]

Because it says pronta, which indicates a female. It would be pronto for a male.

Shouldn't it be 'Ė pronta ad iniziare'?

[Ariaflame]

It might be, but a and i are not the same vowel sounds so it's not mandatory.

[LunarGirl100]

Ok, thanks.

[Diamondswagboyz]

why is it she not he?

As was already answered 4 years ago in the comments that you didn't bother reading. If it was he is ready it would be è pronto, but it's è pronta so it must be she is ready because it has to agree with the implied pronoun.
