: a long period of time I haven't seen her for quite some time.

How do you use quite some time?

A relatively long amount or period of time. It won't be an overnight fix. It will be quite some time before we're able to get the system back to its former state. We hadn't heard from my brother in quite some time, when all of a sudden he appeared on our doorstep.

What does quite some mean?

quite some (something)

Used to signify something very significant, exemplary, or impressive.
