supposition 🔊
Meaning of supposition
An uncertain belief or assumption without conclusive evidence.
Key Difference
Supposition implies a hypothesis or guess, often without firm evidence, whereas synonyms like 'theory' or 'hypothesis' may suggest a more structured or testable idea.
Example of supposition
- His entire argument was based on the supposition that life exists on other planets.
- The detective worked on the supposition that the culprit was someone from the victim's inner circle.
Synonyms
assumption 🔊
Meaning of assumption
Something taken for granted or accepted as true without proof.
Key Difference
An assumption is often accepted as a starting point, while a supposition is more tentative and speculative.
Example of assumption
- She made the assumption that everyone would agree with her proposal.
- The project timeline was built on the assumption that no delays would occur.
hypothesis 🔊
Meaning of hypothesis
A proposed explanation made as a starting point for further investigation.
Key Difference
A hypothesis is more scientific and testable, whereas a supposition is a looser guess.
Example of hypothesis
- The scientist formulated a hypothesis to explain the unusual results.
- His hypothesis about market trends was later proven correct.
conjecture 🔊
Meaning of conjecture
An opinion or conclusion formed on the basis of incomplete information.
Key Difference
Conjecture is more speculative and often lacks any basis, while supposition may have some reasoning behind it.
Example of conjecture
- The historian's conjecture about the ancient text sparked debate.
- Without data, their conclusions were mere conjecture.
presumption 🔊
Meaning of presumption
A belief based on reasonable probability or evidence.
Key Difference
A presumption has a stronger basis than a supposition, often grounded in likelihood.
Example of presumption
- There was a presumption of innocence until proven guilty.
- His presumption that she would say yes turned out to be correct.
theory 🔊
Meaning of theory
A well-substantiated explanation based on evidence and reasoning.
Key Difference
A theory is more rigorously developed than a supposition, which is more of a guess.
Example of theory
- Einstein's theory of relativity revolutionized physics.
- The detective had a theory about how the crime was committed.
speculation 🔊
Meaning of speculation
The forming of a theory or conjecture without firm evidence.
Key Difference
Speculation is broader and can involve multiple guesses, while supposition is a single uncertain belief.
Example of speculation
- Financial speculation drove the stock prices up artificially.
- Media speculation about the celebrity's breakup was rampant.
postulate 🔊
Meaning of postulate
A fundamental assumption used as a basis for reasoning.
Key Difference
A postulate is often used in logical or mathematical contexts, unlike the more general supposition.
Example of postulate
- Euclid's postulates form the foundation of geometry.
- The philosopher's argument rested on a key postulate.
guess 🔊
Meaning of guess
An estimate or conclusion formed without sufficient evidence.
Key Difference
A guess is more casual and less structured than a supposition.
Example of guess
- She took a wild guess at the answer and got it right.
- Without clues, solving the mystery was just a matter of guesswork.
inference 🔊
Meaning of inference
A logical conclusion drawn from evidence and reasoning.
Key Difference
An inference is more reasoned than a supposition, which may lack evidence.
Example of inference
- From his silence, she drew the inference that he was upset.
- The jury made an inference of guilt based on the testimony.
Conclusion
- Supposition is useful when forming initial ideas without full evidence, often serving as a starting point for deeper inquiry.
- Assumption can be used when accepting something as a working truth, even without proof.
- Hypothesis is best in scientific contexts where testable explanations are needed.
- Conjecture fits when making highly speculative claims with little backing.
- Presumption works when there is reasonable probability supporting the belief.
- Theory should be used for well-developed explanations backed by evidence.
- Speculation is appropriate in uncertain scenarios involving multiple possibilities.
- Postulate is ideal in logical or mathematical frameworks requiring foundational assumptions.
- Guess is suitable for informal, less critical situations.
- Inference is strong when drawing conclusions from available evidence.
