What does this sentence mean?⬇
"Your teachers coming to our schools would fulfil the contract."
Especially "Your teachers coming to our schools..."
I do not really know how to understand this.
The confusion is probably because this is an archaic construction. It is called genitive case. Teachers is not the subject of the sentence, although it appears to be because it comes first. The gerund phrase coming to our schools is the real subject, and it belongs to the teachers because it is an action they will undertake.
To be grammatically correct, the sentence should have a possessive apostrophe after teachers: Your teachers' coming to our schools would fulfill the contract.
