To use proscribe in a sentence, name the authority and the thing it bans: “The new rules proscribe mobile phones in exams.” The verb is formal and transitive, and it is most often confused with prescribe, its one-letter neighbour.

What does proscribe mean?
Proscribe is a transitive verb meaning to forbid an activity, ban an item, or declare a person outside the protection of the law. The Cambridge entry for proscribe records the forbid sense as the main one. The word nearly always names an authority, because the ban has to come from somewhere: a statute proscribes, a treaty proscribes, a governing body proscribes.
| Sense | Plain meaning | Example sentence |
|---|---|---|
| Forbid by rule | Officially ban an activity or thing | The treaty proscribes chemical weapons. |
| Outlaw a person | Declare someone outside legal protection | The regime proscribed its critics. |
| Denounce | Publicly condemn an idea or practice | The editorial proscribed the tactic as dishonest. |
One limitation is worth stating. Proscribe is not a general word for dislike or disapproval. A school that merely frowns on hats has not proscribed them; proscription needs a rule with consequences. Where the ban is plain and spoken, ban is the simpler choice, and proscribe reads as the formal register of a written code.
How do you use proscribe in a sentence?
Proscribe takes a direct object, so something is always being forbidden. The five patterns below cover legal writing, academic prose and the historical sense of outlawing a person. The passive is the form legal drafts prefer, because it keeps attention on the banned practice rather than on the body that banned it.
| Pattern | Example | What it signals |
|---|---|---|
| proscribe + noun | The code proscribes late entries. | The object is the forbidden thing. |
| proscribe + noun + from + noun | The law proscribes lobbyists from gifts. | Names who is restrained and from what. |
| be proscribed | Gambling is proscribed in the province. | Passive, standard in legal drafting. |
| proscribe + gerund | The club proscribes smoking indoors. | Presents the activity as an -ing noun. |
| proscribe + person | The senate proscribed three citizens. | The historical outlaw sense. |
The verb never takes an object and an infinitive together. Write the rule proscribes phones, not the rule proscribes students to use phones.

Proscribe in a sentence: examples across contexts
The nine sentences below keep the same verb and move from a school corridor to a treaty chamber. Each row names the part of the meaning doing the work.
| Context | Example sentence | Why this works |
|---|---|---|
| School rule | Our examination code proscribes smart watches of every kind. | A written code supplies the authority the verb needs. |
| Legal writing | The statute proscribes the sale of fireworks to minors. | Names the prohibited act with a precise object. |
| Treaty text | The treaty proscribes the testing of nuclear devices. | Formal register with an impersonal, binding subject. |
| Academic prose | Most journals proscribe the use of unpublished data. | Extends the word to a scholarly rule with consequences. |
| News report | The council proscribed street trading after a wave of complaints. | Names the body, the ban and the reason. |
| History essay | The emperor proscribed the leading families and seized their land. | Uses the outlaw-a-person sense accurately. |
| Workplace policy | The policy proscribes personal calls during client meetings. | Applies the verb to a modern, ordinary rule. |
| Sports ruling | The federation proscribed the substance without naming a single brand. | Shows the passive-friendly official register. |
| Conversation | She proscribed any mention of the merger at dinner. | An informal ban, still transitive and slightly playful. |
Notice that the sentence collapses if you remove the authority. A proscription with no code, court or council behind it sounds like an opinion, which is exactly what the verb is meant to exclude.
Proscribe vs prescribe and prohibit
Proscribe is confused with prescribe more than with any other word, because the two differ by a single letter and mean opposite things. Prohibit is the closest true synonym, and all three verbs belong to formal registers.
| Attribute | proscribe | prescribe | prohibit |
|---|---|---|---|
| Core meaning | Forbid officially | Order, recommend or give | Forbid by authority |
| Direction | Takes permission away | Gives instruction | Takes permission away |
| Typical object | Practice, weapon, conduct | Medicine, treatment, rule | Action, item, entry |
| Register | Formal and academic | Formal and medical | Formal to neutral |
| Example | The statute proscribes the practice. | The doctor prescribed rest. | The sign prohibits parking. |
Verdict: choose prescribe when someone gives or orders a remedy, prohibit when you want a familiar formal word, and proscribe when a written rule bans a practice or a person. A memory hook that works for many learners is that proscribe shares its opening with prohibit, and both take something away.
Forbid and disallow are plainer still, and both fit conversation where proscribe would sound stiff.
Word forms and grammar of proscribe
Proscribe inflects regularly, and its noun proscription is the form that appears most in headings and indexes. The noun proscription compresses the whole act of banning into one word.
| Form | Part of speech | Example |
|---|---|---|
| proscribe | verb, base form | The charter proscribes secret trials. |
| proscribes | verb, third person singular | Custom proscribes open criticism of the chair. |
| proscribed | verb, past and past participle | The practice was proscribed last year. |
| proscribing | verb, present participle | The act is proscribing a long-standing custom. |
| proscription | noun | The proscription took effect in March. |
| proscriptive | adjective | The rules are too proscriptive for a small club. |
Keep the adjective proscriptive apart from prescriptive. A proscriptive rule forbids; a prescriptive one lays down what should be done, and the second is far more common in writing about teaching.

The bottom line
Use proscribe in a sentence when a written rule forbids a practice, an item or a person, and name the authority doing the forbidding.

In everyday writing, a plainer denounce or forbid often reads better.
