assumption 🔊
Meaning of assumption
A thing that is accepted as true or as certain to happen, without proof.
Key Difference
An assumption is often a belief taken for granted without verification, whereas its synonyms may imply varying degrees of evidence or reasoning.
Example of assumption
- Her assumption that the meeting was canceled led to confusion when everyone showed up.
- The scientist's assumption about the chemical reaction was later proven incorrect.
Synonyms
presumption 🔊
Meaning of presumption
An idea that is taken to be true based on probability rather than proof.
Key Difference
A presumption often carries a slightly stronger sense of being based on reasonable grounds, while an assumption may be more speculative.
Example of presumption
- The court worked on the presumption of innocence until proven guilty.
- His presumption that the project would be easy led to poor planning.
supposition 🔊
Meaning of supposition
An uncertain belief or theory based on limited evidence.
Key Difference
A supposition is more tentative than an assumption and is often used in hypothetical reasoning.
Example of supposition
- Her supposition that aliens might exist is based on unexplained phenomena.
- The detective’s supposition about the suspect’s alibi turned out to be correct.
hypothesis 🔊
Meaning of hypothesis
A proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Key Difference
A hypothesis is more formal and scientific, often requiring testing, whereas an assumption may remain untested.
Example of hypothesis
- Einstein’s hypothesis about relativity revolutionized physics.
- Her hypothesis that plants grow faster with music was tested in an experiment.
conjecture 🔊
Meaning of conjecture
An opinion or conclusion formed on the basis of incomplete information.
Key Difference
Conjecture implies more guesswork and less certainty than an assumption.
Example of conjecture
- The historian’s conjecture about the ancient civilization’s fall was debated for years.
- Without data, his claims remained mere conjecture.
postulate 🔊
Meaning of postulate
A thing suggested or assumed as true as the basis for reasoning or discussion.
Key Difference
A postulate is often used in logical or mathematical contexts, whereas an assumption is more general.
Example of postulate
- Euclid’s postulates form the foundation of classical geometry.
- The economist’s postulate about market behavior was widely accepted.
premise 🔊
Meaning of premise
A statement or proposition from which another is inferred or follows as a conclusion.
Key Difference
A premise is foundational in logical arguments, while an assumption may not always be explicitly stated.
Example of premise
- The argument’s premise was that all humans desire happiness.
- If we accept his premise, the conclusion logically follows.
belief 🔊
Meaning of belief
An acceptance that something exists or is true, especially without proof.
Key Difference
A belief is more personal and subjective, while an assumption is often more neutral.
Example of belief
- His belief in karma influenced his decisions.
- The ancient civilization’s belief in multiple gods shaped their culture.
theory 🔊
Meaning of theory
A supposition or a system of ideas intended to explain something.
Key Difference
A theory is more structured and evidence-based than an assumption.
Example of theory
- Darwin’s theory of evolution changed biology forever.
- Her theory about memory formation was supported by experiments.
inference 🔊
Meaning of inference
A logical conclusion or deduction based on evidence and reasoning.
Key Difference
An inference is derived from evidence, while an assumption may lack supporting proof.
Example of inference
- From the footprints, the tracker made an inference about the animal’s size.
- Her inference that he was lying came from his nervous behavior.
Conclusion
- An assumption is a starting point in reasoning, often accepted without verification.
- Presumption can be used when there is reasonable but not certain grounds for belief.
- Supposition works best in hypothetical or uncertain scenarios.
- Hypothesis is ideal in scientific contexts where testing is involved.
- Conjecture is useful when making educated guesses without solid evidence.
- Postulate fits well in mathematical or logical frameworks.
- Premise is key in structured arguments where foundational statements are needed.
- Belief applies to personal convictions rather than neutral assumptions.
- Theory should be used when explaining phenomena with structured evidence.
- Inference is best when drawing conclusions from observable facts.
