Words to Avoid in Communication

Words to avoid according to Giovanni Ceroni's NLP: why "no," "sorry," "don't," "try" and "hope" weaken communication, and what to say instead.

Words are just the steering wheel. The real goal is the direction. Whoever chooses words that regulate state is the one driving.

What it is

There are certain everyday words and expressions that, while seeming harmless, produce precise, often unwanted neurological effects: they trigger doubt, passivity, opposition or limiting beliefs. Recognizing them and replacing them with more effective alternatives is a practical communication skill in NLP.

Why it matters

Every habitual word is, in a sense, a neurological habit: used consistently, it helps shape how a person thinks, reacts, and gets perceived by others. Working on these words isn't a matter of linguistic etiquette, but of real psychological positioning, with measurable effects on the internal state of both speaker and listener.

How it works

"No" at the start: it's one of the most dangerous words in communication, often used without any real intention to oppose ("no, look..." "no, wait..."). The other person's brain, though, registers the signal before the content: it communicates "I'm correcting you, I'm opposing you," generating a micro-friction that turns a cooperative conversation into a defensive one. The effective substitute is the "Yes, and..." structure, which communicates "I heard you, I can add without erasing you."

"Sorry," "bother," "steal": expressions like "sorry to bother you" or "let me steal a minute of your time" send the other person's nervous system three implicit messages: "I'm invading your space," "what I'm bringing is worth little," "you have more power than me right now." Replacing them with "do you have two minutes?" or "is this a good time?" instead communicates respect for the other person's time and value for what you're bringing, positioning yourself adult to adult instead of shrinking yourself.

Negation ("don't/not"): at a first level of processing, the brain doesn't effectively process negations. To not think about or not do something, it first has to represent that very thing: telling a child "don't drop the bowl" risks making them picture exactly the bowl falling. It's more effective to give a direct positive instruction: "pay attention while carrying the bowl to the table," or, before an exam, "breathe deeply" instead of "don't get nervous."

"Try to": it's a modal operator that automatically introduces doubt about success. Saying "I'll try" communicates uncertainty, and the brain also listens to the degree of certainty contained in the words: if the language is uncertain, the internal state tends to be too. A direct, resolute instruction, delivered gently, is more effective: not "try to imagine," but "imagine."

"Hope": it puts the speaker in a passive stance, in "hopeful waiting," activating the serotonin of anticipation instead of the dopamine of motivation. A passive attitude rarely generates real change. It's more effective to turn "I hope I succeed" into "I'm committing to doing this": something that was previously left to external factors (time, luck, circumstances) becomes the person's responsibility and action.

"I can't, I'm unable, I just can't do it": these are statements of learned helplessness, which reinforce specific neurological circuits with every repetition, deepening a neural groove that becomes easier and easier to fall into. A practical technique for intervening consists of having the person repeat the sentence while adding "for now" or "yet" (for example "I can't lose weight yet"), observing how the internal feeling tied to that belief changes, then asking "what would happen if you did manage it?"

Common mistakes

A common mistake is treating these linguistic adjustments as simple stylistic formalities, instead of as real levers on the listener's neurochemical state. A second mistake is applying the substitutions mechanically, without understanding the general principle that justifies them (giving direction instead of doubt, responsibility instead of passivity). A third mistake is correcting your words only in communication toward others, forgetting the same effects apply to internal dialogue.

Practical example

A person preparing for an important interview tells themselves internally "I hope I don't get too nervous and manage to answer well." This sentence contains, all at once, a negation ("don't get nervous," which the brain processes by picturing the very nervousness), a passive attitude ("hope"), and a modal operator of doubt ("manage to"). Reformulated according to the principles above, it becomes something like: "I'm committing to answering calmly, breathing deeply before each question" — a positive, direct, action-oriented instruction, free of doubt.

Applications

These linguistic distinctions apply to coaching, parenting, communicating with work teams, mental preparation for performance and exams, and generally to everyday internal dialogue, where the same words applied to oneself produce the same neurochemical effects observed in communication toward others.

Frequently asked questions

Why is "no" at the start of a sentence problematic even when you don't mean to oppose?

Because the listener's brain registers the signal before the content: an opening "no" communicates correction and opposition, turning the tone of the conversation from cooperative to defensive, regardless of the real intention.

Why doesn't the brain process negations like "don't do" well?

Because to not picture something, the mind first has to picture it: saying "don't fall" first activates the image of falling. A direct positive instruction ("pay attention") is more effective.

What's problematic about the word "try"?

It introduces a modal operator of doubt about the success of the action. The brain listens to the degree of certainty in the language: saying "imagine" instead of "try to imagine" communicates a clearer, more resolute direction.

Why is "hope" less effective than "commit"?

Because hoping puts you in a passive stance, activating waiting instead of motivation to act. Committing shifts responsibility for the outcome from outside (luck, circumstances) to inside the person.

How can you work on beliefs like "I can't do it"?

A practical technique is having the person repeat the sentence while adding "for now" or "yet," observing how the internal feeling changes, to open up the possibility of future change instead of freezing a permanent impossibility.
