A conversational filler is a word or phrase that we use in speech to buy thinking time, such as basically, you know, kind of, sort of, actually, like and so yeah. In formal writing and prepared speeches they add no meaning and lower the register.
This lesson belongs to audience, purpose and register. It connects directly to choosing a register for a letter to an institution, where a single filler can undo an otherwise careful paragraph.
Why do fillers matter for a reader?
A reader or listener judges your control from small signals. Fillers signal that you are thinking aloud rather than presenting a planned point.
There are three common groups.
- Softeners: kind of, sort of, a bit. They make a claim vague.
- Connectors that add nothing: so yeah, anyway, like I said.
- Emphasis words used out of habit: basically, actually, literally, really.
The test is simple. Delete the word. If the meaning is unchanged, it was a filler.
Worked example
Task: Improve this paragraph from a report to the school council.
Basically, the canteen is kind of too crowded at lunch. Actually, most students have to wait like twenty minutes, so yeah, it is a problem.
Step 1, underline the fillers: Basically, kind of, Actually, like, so yeah.
Step 2, delete and read what is left:
The canteen is too crowded at lunch. Most students have to wait twenty minutes. It is a problem.
Step 3, check for lost meaning. Nothing important is missing. Like twenty minutes also made the number sound unsure, so the plain figure is stronger.
Step 4, replace weak words with precise ones. “Too crowded” can become “overcrowded”, and “a problem” can say what kind of problem.
The canteen is overcrowded at lunch. Most students wait twenty minutes to be served, which leaves little time to eat.
The final version has fewer words in some places and more in others, and every word now has a job.
The mistake to watch for
Some students remove one filler and let another take its place.
Mistaken version: The canteen is truly, honestly overcrowded. To be honest, students really have to wait a long time.
Truly, honestly, to be honest and really are the same habit in new clothes. Emphasis words do not prove a point. A fact does.
Corrected version: The canteen is overcrowded. Students wait twenty minutes to be served.
Another slip is deleting every informal phrase from dialogue in a story. There, a filler such as “you know” can be a deliberate choice to make a character sound real. The skill is to decide, not to delete automatically.
Check yourself
1. Circle the fillers: “So basically, the new timetable is kind of confusing, you know?”
Show answer
So basically, kind of, you know. A cleaner version: “The new timetable is confusing.”
2. Replace the vague filler with a specific detail: “The hall was really, really loud.”
Show answer
For example: “The noise in the hall drowned out the announcements.” A concrete effect is stronger than repeated emphasis.
3. A student writes dialogue: “Well, you know, I just thought, like, maybe we could go.” Should the fillers be removed?
Show answer
Not automatically. In dialogue they can show hesitation and make the speaker sound real. Keep them if the hesitation matters to the scene, but keep them out of the narration and formal writing.
Where this leads next
The skill now moves to the start and end of a piece, where register is most visible, in making opening and closing choices fit the task. You can test all five lessons with the practice set.
A quick way to catch fillers is to compare drafts in the writing revision compare view. If you would like someone to hear your drafts read aloud and flag each filler, a teacher in online one-to-one English First Language tuition can do that with you.
