Supposition in a Sentence: Meaning & Examples

A supposition is an idea believed to be true even though it has not been proved, and it often appears in formal writing as “the supposition that…” or “on the supposition that….” In a supposition sentence, name the idea and show whether evidence supports it; a supposition is not automatically a fact.

• Part of speech: supposition is a noun.
• Meaning: an idea believed possible or true without proof.
• Common pattern: “the supposition that…” followed by a clause.
• Other patterns: “on the supposition that,” “supposition about,” and “pure supposition.”
• Evidence: a supposition may be reasonable, mistaken, or still untested.

What does supposition mean?

Cambridge Dictionary defines supposition as believing something is true without proof, or the idea believed. The word can be countable (“a supposition”) or uncountable (“pure supposition”). Oxford also describes it as a formal idea that may not be provable, and lists common patterns such as “supposition that” and “on the supposition.” Oxford Learner’s Dictionary.

A supposition is not the same as a verified conclusion. It can be a useful starting point for reasoning, but the sentence should make clear whether the speaker is guessing, setting a condition, or reporting evidence. Words such as reasonable, mere, and pure often tell readers how the writer evaluates the idea.

How do you use supposition in a sentence?

The most direct pattern is supposition that + clause: “We began with the supposition that the room was empty.” Use on the supposition that when one action depends on an idea, or supposition about before a subject. The noun is formal, so guess or assumption may sound more natural in casual conversation.

• supposition that: “Her conclusion rested on the supposition that every witness had seen the same event.”
• on the supposition that: “On the supposition that the bus was late, we waited inside.”
• supposition about: “The report tested a supposition about how the river changed course.”
• uncountable use: “Without measurements, the claim remains pure supposition.”

Supposition sentence examples

Supposition, assumption, and fact

Supposition and assumption are often synonyms, especially when a writer means an idea accepted without complete proof. The useful distinction is not a rigid dictionary rule; it is how the writer frames the evidence. Calling something a supposition signals uncertainty, while calling it a fact says it has been established. Avoid treating a plausible supposition as proof.

For example, “The team assumed the meeting was canceled” reports what the team believed. “The supposition that the meeting was canceled spread quickly” emphasizes the unconfirmed idea. If reliable evidence later confirms the cancellation, the sentence can state that result directly.

Frequently asked questions about supposition

What does supposition mean?

Supposition means an idea or belief accepted as possible or true without enough proof to establish it as fact. The noun can refer to one particular idea, as in “a reasonable supposition,” or to unproved belief more generally, as in “pure supposition.”

How do you use supposition in a sentence?

Use supposition with a that-clause to state the idea: “The plan rested on the supposition that the bridge would reopen.” You can also write “on the supposition that” or “a supposition about” a topic. Add evidence or a qualification when readers need to know how certain the idea is.

Is supposition countable or uncountable?

Supposition can be countable or uncountable. Use “a supposition” or “several suppositions” for individual ideas; use it without an article in phrases such as “based on supposition” or “pure supposition.” Oxford and Cambridge both record count and noncount uses, so either form is standard.

Is supposition the same as assumption?

Supposition and assumption often mean nearly the same thing: an idea treated as true without full proof. Supposition is more formal in tone and commonly appears in patterns such as “the supposition that.” Neither word proves the idea; state what evidence supports it before presenting a conclusion as fact.

Use supposition precisely

A clear supposition sentence identifies the unproved idea and gives readers its status. Use “supposition that” to state a full proposition, “supposition about” to name a topic, and “pure supposition” when evidence is absent. Then show what would confirm or disprove the idea.
