English Fillers: When and How to Use "Um," "Ah," and More

What Are Filler Words?

Filler words are natural pauses in speech that English speakers use while thinking or transitioning between ideas. While we shouldn't overuse them, using them appropriately can actually make your English sound more natural.

Common English Fillers

Here's a guide to the most common fillers and when to use them:

Filler	Sound	When to Use	Example in Context
Um	/ʌm/	When thinking deeply	Um... let me think about that.
Uh	/ʌ/	Quick pause or correction	I went to, uh, Paris last year.
Ah	/ɑː/	Realizing something	Ah, now I remember!
Well	/wel/	Starting a response	Well, that's an interesting point.
Like	/laɪk/	Explaining or example	It was, like, really amazing.
You know	/juː nəʊ/	Checking understanding	It was difficult, you know?
I mean	/aɪ miːn/	Clarifying a point	I mean, that's what I think.

Natural Usage Patterns

1. Thinking Time

When you need a moment to think, use:

• Um... (longer pause)
• Uh... (shorter pause)

Example Conversation:
A: What did you do last weekend?
B: Um... I mostly stayed home and, uh, caught up on some reading.

2. Self-Correction

When fixing a mistake, use:

• Uh, I mean...
• Or, well...

Example:
I met him on Tuesday... uh, I mean, Wednesday.

3. Starting Responses

When beginning to answer, use:

• Well...
• Ah...

Example:
A: What do you think about the new policy?
B: Well... it has both advantages and disadvantages.
