Etymology

Origin of inseparable

First recorded in 1350–1400; Middle English word from Latin word insēparābilis. See in- 3, separable

Explanation

People or things that are inseparable can't be separated. It's like they're glued together. Usually, this word applies to people and is a bit of an exaggeration. Two friends who hang out every day are considered inseparable. Two people who are in love and spend most of their time together are inseparable. It's not that they can't be separated, but they don't want to be. Inseparable people love being together.
