rigor

/ˈrɪgər/

/ˈrɪgə/

Other forms: rigors

When a school boasts of its academic rigor, it means its students learn a lot and work really hard. Rigor means thoroughness and exhaustiveness — the gold standard for a good teacher.

You may have heard of "rigor mortis" — which is a medical term describing the stiffness of a body after death. Another meaning of rigor is "sternness or severity" — for many, the rigors of boot camp are not easy to endure.
