Questions about example sentences with, and the definition and usage of "Until"

A: “If”is incorrect in this sentence not because it is grammatically incorrect, but because it makes the sentence mean the opposite of what it is intended.

“Until” in this sentence can be substituted with “unless” and that will keep the same meaning.

In other words, the sentence means “you will always call things that happen to you ‘fate’ unless or until you control your subconscious.”

A: It means the store or shop is closed until they announce that it's open again.

A: Something did not happen until a month passed.

It wasn't until a month passed until my package arrived -> This means the package arrived only after a month passed.

That formula is usually used when something already happened. For example, it's May now and you're telling the story of how you ordered a package in January but it wasn't until February until it arrived. It wasn't until a month went by that your package arrived.

A: There is no real difference in how/when they are used.
Anywhere where you would say ‘until’ you could say ‘till’ instead (and vice versa)!

A: 'You can stay over until 8 PM'

'You can stay unless my parents come home'

A: Just say how long will you be out I think that would make more sense

A: Yes.You can. :)

A: Yes, either "late" or "until late" will do.
