Etymology

Origin of insert

First recorded in 1520–30; from Latin insertus, past participle of inserere “to put in, insert,” equivalent to in- “in” + ser- (stem of serere “to link together”) + -tus past participle suffix; see in- ²

Explanation

When you insert something or someone, you put it into something else. You could insert yourself into a conversation, or you could insert a comma into the sentence you just wrote. The verb insert comes from the Latin in-, meaning “into,” and serere, meaning "to join." When you insert yourself into a conversation, you’re joining in, whether your friends want you to or not. Insert can also mean to fit snugly into, or to tuck. You might fit a card into an envelope that fits it perfectly, or insert first one leg and then another into a pair of tights.
