Use The Word Prohibit In A Sentence | Quick Usage Tips

Prohibit is a formal verb that turns up in rules, laws, school handbooks, and workplace policies. When you can control it, your sentences sound clear and firm instead of stiff or vague.

The word usually means to officially refuse to allow something or to prevent an activity by law or authority. Cambridge Dictionary explains it this way, and other major dictionaries follow the same idea.

Many learners type “use the word prohibit in a sentence” into a search bar because the verb feels strict and legal. This article breaks that task into simple patterns and examples so you can use it with confidence.

Meaning Of Prohibit And Core Grammar

Prohibit is a regular verb. The base form is prohibit, the third-person singular form is prohibits, the -ing form is prohibiting, and the past tense and past participle are prohibited. It always takes an object, so you prohibit something or prohibit someone from doing something.

In plain terms, you use prohibit when a rule, law, policy, or person in authority blocks an action. Merriam-Webster notes that it means to forbid or prevent something by authority, which matches real use in legal texts, contracts, and public signs.

You can shape sentences with prohibit in several reliable patterns. The table below shows the most common structures and when each one fits.

Pattern	Example Sentence With Prohibit	When This Pattern Fits
prohibit + noun	The new rules prohibit smoking inside the building.	When a rule blocks an activity in general.
prohibit + people + from + -ing	The school prohibits students from using phones during exams.	When authority stops a group from doing something.
be + prohibited + from + -ing	Employees are prohibited from sharing passwords.	When you need formal, written policy language.
be + prohibited + by + noun	The event was prohibited by local law.	When the law or authority should appear as subject.
regulations/ rules + prohibit + -ing	City regulations prohibit parking on the grass.	When the focus stays on the type of rule.
prohibit + noun phrase	This policy prohibits any use of personal email for work.	When you want a strong ban on a clear practice.
prohibit + noun + altogether	The club constitution prohibits gambling altogether.	When no exceptions exist for a behaviour.

Notice that prohibit usually links rules and actions. The person or document with power stands on one side of the verb, and the blocked action or group stands on the other side.

How To Use The Word Prohibit In A Sentence Correctly

When you write with prohibit, it helps to build the sentence in three short steps: choose who has the power, decide what action they stop, then pick the pattern that fits.

Step One Choose The Subject With Power

The subject of a sentence with prohibit is usually a person, group, rule, or law that has authority. Common subjects include words such as government, company, school, policy, regulation, or law.

You might write, “The government prohibits imports of unsafe products,” or “School rules prohibit hats in class.” In both lines, the subject clearly has control over the action that follows.

Step Two Add The Blocked Action

Next, add the action that is not allowed. This action often appears as a noun or as a verb ending in -ing. You can say, “The park rules prohibit camping overnight,” or “Company policy prohibits employees from posting client data online.”

In each case, the verb links a source of authority with a blocked action. Readers can see at a glance who cannot do what.

Step Three Pick The Right Pattern

The patterns in the first table act like templates. Once you know whether the subject is a law, a person, or an organisation, you can drop in the correct pattern and adjust details such as tense or time phrases.

Using Prohibit With A Direct Object

In many cases, prohibit takes a direct object without extra words. Sentences such as “Local rules prohibit fireworks” or “The contract prohibits side jobs” are short and clear. This style works well in headlines, notes, and warning signs.

Using Prohibit With From And An -Ing Verb

When you need to show who cannot do something, add a person or group before the verb and the word from plus an -ing verb after it. “The club prohibits members from drinking alcohol on site” and “The captain prohibits passengers from entering this area” both follow this pattern.

Prohibit works in all usual tenses. You can say “The law prohibits,” “The law prohibited,” or “The law will prohibit” depending on time. You can also use negative forms such as “The rules do not prohibit quiet conversation,” which tells readers that an action is allowed.

Quick Checks Before You Use Prohibit

• Ask who has the power in the situation; make that your subject.
• State clearly what action, object, or behaviour is not allowed.
• Pick a pattern from the table that matches your subject and action.
• Keep the sentence short so the rule feels firm and easy to read.

Using The Word Prohibit In A Sentence In Everyday English

Prohibit sounds more formal than verbs such as ban or stop. You often see it in written rules, legal documents, contracts, and announcements from official bodies. In spoken English, many people switch to simpler verbs, yet prohibit stays common in serious writing.

If you feel that prohibit is too stiff for a casual text, you can swap it for verbs such as forbid, ban, or stop. When you write about laws, regulations, or policy documents, though, prohibit sends the right formal signal and keeps your style close to standard references.

When Prohibit Works Best

Prohibit fits best when a rule is clear, firm, and not open to personal choice. It often appears with topics such as age limits, safety rules, financial dealings, and digital security.

Here are some examples that show natural everyday use:

• The rental contract prohibits pets in the apartment.
• Local law prohibits selling alcohol to minors.
• The stadium prohibits bringing glass bottles through the gate.
• Company policy prohibits copying client files to personal devices.
• The website prohibits users from sharing their passwords.

Choosing Between Prohibit And Forbid

Both verbs relate to stopping something. Prohibit usually appears with a written rule in the background, such as a law, regulation, or company policy. Forbid often feels more personal, as when parents forbid a child from playing a video game or a teacher forbids side conversations during class.

In many cases, you can use either verb. If you are quoting or paraphrasing legal or technical sources, though, prohibit is the safer choice because it matches the wording used in dictionaries and reference texts.

Common Mistakes With Prohibit And How To Fix Them

English learners tend to repeat the same slips when they write with prohibit. Most of these issues come from mixing verb patterns, leaving out from, or choosing the wrong tense.

The table below lists frequent mistakes side by side with cleaner versions.

Incorrect Sentence	What Feels Wrong	Better Sentence
The school prohibits to use phones in class.	Uses to instead of from plus -ing.	The school prohibits students from using phones in class.
Smoking is prohibit in this area.	Uses the base form instead of prohibited.	Smoking is prohibited in this area.
The rules prohibit to park here.	Infinitive pattern sounds unnatural with prohibit.	The rules prohibit parking here.
The law prohibited citizens to vote twice.	Missing from before the -ing verb.	The law prohibited citizens from voting twice.
They are prohibited to enter the lab without goggles.	Passive pattern does not use to in this way.	They are prohibited from entering the lab without goggles.
The manager prohibits that staff are late.	Clumsy clause after the verb.	The manager prohibits staff from arriving late.

Most of these problems disappear once you remember one simple rule: after prohibit, you either place a noun or use from plus an -ing form. If a sentence looks long and tangled, check whether you tried to follow it with a full clause starting with that; a shorter noun or -ing phrase nearly always works better.

Swap in your own subjects, actions, and settings, and you have a clear sentence that follows standard patterns.

Final Tips For Using Prohibit Effectively

Prohibit is a compact way to show that rules block an action. Once you know the core patterns, you can shape sentences that sound natural in school essays, reports, emails, and formal letters.

Keep three ideas in mind. Pick a subject with real authority, state the blocked action in a short phrase, and choose either a direct object or a from + -ing pattern. Do that, and prohibit will feel like a steady tool in your English rather than a verb you avoid.
