Other forms: sabbaticals
If your job entitles you, you probably take a sabbatical every seven years, which means you get a year of paid leave to do whatever you want to further your understanding of the world.
The word sabbatical, which can be a noun or an adjective, comes from the Greek word sabatikos, which means “of the Sabbath,” the day of rest that happens every seventh day. Most teaching jobs come with the promise of a sabbatical, which is a year of not having to teach, though you still get paid. During your sabbatical, you usually are expected to do research and perhaps write a book — in other words, keep working.
