be in use

I have no idea how long the well has been in use.

No words were in use later than the 17th century.

The school was in use from 1979 until late 2001.

The new building was in use for the 1953-54 school year.

The building had been in use as a school house since the 1920s.

The name for the river was in use by 1904.

By the end of last year more than 7,200 were in use.

At the time, the table in common use was from 1983.

The system had been in use for some 50 years.

Since 1985, the church has no longer been in use.
