Filler words aren't filler. They're doing real work in the sentence.

'Like,' 'I mean,' and 'you know' carry meaning of their own. Missing them means missing part of what's actually being said.

It's easy to write these off as noise: extra sounds a speaker throws in out of habit, safe to ignore while you listen for the “real” content. That's a mistake. These words are called discourse markers by linguists for a reason: they signal hedging, agreement-seeking, topic shifts, and tone, and missing them means missing part of the actual message, not just some background noise around it.

Five Markers, Decoded

What each one is actually signaling, beyond just taking up space.

Like

Softening or hedging a claim

Not always meaningless. "Like" often signals that what follows is approximate, not exact, or that the speaker is choosing their next words carefully. Cutting it doesn't always keep the same meaning.

"It was, like, really weird" softens the claim compared to the flatter "It was really weird."

I mean

Reframing or softening an opinion

Usually signals a shift: either restating something more precisely, or cushioning an opinion that's about to sound blunt.

"I mean, it's not that deep" softens the opinion that follows, making it sound less like a firm judgment.

You know

Checking for shared understanding

A quick check-in that the listener is following along, or an implicit request to fill in a detail the speaker is skipping over.

"It was just, you know, a lot" assumes the listener can fill in what "a lot" means without more detail.

Right?

Seeking agreement mid-sentence

Dropped in to invite quick agreement or confirm the listener is still tracking, functioning almost like a mini question buried inside a statement.

"That meeting ran forever, right?" invites a quick nod more than an actual answer.

So, anyway

Signaling a return to the main point

A verbal marker that a tangent has ended and the speaker is steering back to what they were originally saying.

"So, anyway, back to what I was saying" is a clear audio cue that a detour is over.

THE REAL TEST

Try removing one of these words from a sentence you've heard. If the meaning shifts even slightly, it wasn't filler.

Four Jobs These Markers Are Doing

Most discourse markers fall into one of these functions, sometimes more than one at once.

Hedging

Softening how certain or definite a statement sounds, so it lands as an opinion rather than a hard fact. "Like" and "I mean" do most of this work.

Checking in

Quietly confirming the listener is still following, or inviting quick agreement without pausing the conversation to ask directly. "You know" and "right?" both do this.

Transitioning

Signaling a shift back to the main point after a tangent, or moving from one idea to the next without a formal announcement. "So, anyway" is the clearest example.

Buying time

Giving the speaker a beat to choose their next words, without going silent. This overlaps with hedging, but the job here is timing, not softening meaning.

Why This Matters for Listening, Not Just Speaking

Most English instruction treats these words as something to avoid producing, since they can sound unpolished in formal writing. But for listening comprehension it's the opposite problem: these markers show up constantly in real conversation, and if your ear is trained to tune them out as noise, you lose the hedge, the tone shift, or the agreement check they were actually carrying.
