Cession vs. session

Cession refers to (1) the act of ceding or surrendering something, and (2) something that is ceded. Session can refer to several things, including (1) a period of time devoted to a specific activity, (2) a meeting of a legislative or judicial body, and (3) a term at a school or university.

Both words only function as nouns, and they sound the same. Otherwise, they have no common ground. Still, they’re occasionally mixed up—for example:
