Filler word

Definition

A sound, word, or phrase — like "um," "uh," "like," or "basically" — that fills a pause in speech without adding meaning.

Filler words are universal in human speech. They signal that the speaker is still thinking, holding their place in a conversation, or transitioning between ideas. In casual conversation they smooth speech; in high-stakes presentations they can feel unprepared.

Linguists distinguish two types: filled pauses (sounds like "um" and "uh") and discourse markers (real words used as filler, like "like" and "basically"). Both categories are reduced through deliberate practice — the goal isn't to eliminate them but to keep them from drowning out your real ideas.
