Filler Words: Enemy or Tool?

Filler Words: Enemy or Tool?

Filler Words: Enemy or Tool?

Most English courses teach one rule:

“Avoid filler words.”

So learners try to delete:

  • um
  • uh
  • like
  • you know

But something strange happens.

When they remove fillers:

  • pauses get longer
  • speech sounds robotic
  • confidence drops

Because fillers are not always the enemy.
At B2+, they become a professional communication tool.


Two Types of Fillers

1) Translation Fillers (B1)

These appear when the brain is searching:

  • “uhhh…”
  • long silence
  • switching to native language

Signal:

processing problem


2) Discourse Fillers (B2+)

These organize thought:

  • “actually…”
  • “to be honest…”
  • “the thing is…”
  • “I mean…”

Signal:

communication strategy


The Filler Spectrum

LevelTypical FillersWhat It Means
A2long “uhhhh”word searching

When Fillers Help You

1) Buying Thinking Time

“That’s an interesting question… let me think.”

Better than silent panic.


2) Softening Opinions

“To be honest, I’m not fully convinced.”

More diplomatic than:

“I disagree.”


3) Organizing Stories

“So, the main issue was…”
“What happened next was…”

Creates listener-friendly structure.


When Fillers Hurt You

1) Before Verbs

“I… uh… decided…”

Classic translation signal.


2) Repetitive Crutches

Saying “like” 12 times in a minute.


3) Native-Language Escape

Switching to L1 to think.


The Professional Filler Set

Replace These:

  • uh
  • um
  • err

With These:

  • “the point is…”
  • “from my perspective…”
  • “what I’m trying to say is…”
  • “in other words…”

This is the jump from B1 → B2.
