The most dangerous three-letter word in communication?

It’s only three letters long.

We use it dozens of times a day.

And yet, in my experience as a communication coach, it quietly sabotages more conversations than almost any other word.

Consider these examples:

'You did a great job on the presentation, but…'

'I understand your concerns, but…'

'I agree with you, but…'

'I’d love to help, but…'

What happens to us when we hear the word but?

For many people, everything before it disappears.

The compliment feels diluted.

The understanding feels conditional.

The agreement feels temporary.

The person wouldn't ‘love’ to help

The listener starts preparing for impact.

Why our brains notice the ‘but’

Human beings are naturally wired to scan for threat, criticism and potential problems.

So when someone says:

'You handled that meeting really well, but…'

many of us don’t take in the ‘really well’ and brace ourselves for the real message.

The positive opening becomes a primer for the criticism that follows.

This is why feedback that begins with praise and then pivots sharply into a but can sometimes feel insincere, even when the speaker has the best of intentions.

One alternative: 'and'

An experiment is to replace but with and.

Instead of:

'You did a great job presenting, but I’d like you to be more concise.'

Simply try;

'You did a great job presenting, and I’d like you to be more concise.'

The difference is subtle, but significant.

The first sentence suggests one statement cancels out the other. The second allows both statements to be true at the same time.

You performed well. And there is room to improve.

Both can coexist in harmony.

Leadership and multiple truths

One of the hallmarks of mature communication is the ability to hold multiple truths simultaneously.

A leader might say:

'I understand this change is frustrating, and it’s still necessary.'

'Your concerns are valid, and we still need to make a decision.'

'I respect your point of view, and I see the situation differently.'

Notice how the conversation feels less combative. Less like a debate and more like a discussion.

The word and tends to create space. The word but can create opposition.

But ‘but’ isn’t evil!

I’m not suggesting we ban the word entirely. Sometimes but is exactly the right word. Language is nuanced.

The real lesson here is awareness.

Many of us use but automatically, without realising the effect it can have on the listener. A small change in one word can alter the emotional tone of an entire conversation.

A challenge

Over the next few days, listen out for how often you use the word but.

Notice when others use it too.

Then just experiment.

Replace a few of those buts with ands.

You may be surprised how much more collaborative, constructive and considerate your conversations become.

Because sometimes changing a small word can make a big difference.

Drawing on my background in actor training, storytelling, psychology, and behavioural science, I work with leaders and professionals across London and the UK to communicate with greater confidence, influence, and authenticity. Together, we develop the skills to engage audiences, shape compelling narratives, and inspire action in the moments that matter most.
