Hypothesis – Definition and Part of Speech
A hypothesis is a proposed explanation or conjecture made on the basis of limited evidence as a starting point for further investigation. It serves as a foundational element in scientific research, where it is tested through experimentation and observation. The word “hypothesis” functions primarily as a noun but can also be used informally in other forms like adjective (“hypothetical”).

Usage Notes
-
Conjecture: Often used in academic and formal writing where a hypothesis might not yet be fully substantiated. Suitable when emphasizing the preliminary nature of an idea.
-
Theory: Used extensively within scientific contexts to describe hypotheses that have gained substantial empirical support. It carries more weight than “hypothesis” due to its evidence-backed status.
-
Supposition: Favored in situations requiring a degree of caution or skepticism. Appropriate for business or formal settings where the reliability of an assertion is in question.
-
Speculation: Commonly used in casual and conversational contexts, especially regarding future events or trends without solid evidence (e.g., financial speculation).
-
Proposition: Often found in debates and philosophical discourse. It suggests that something has been offered up for discussion rather than conclusively established.
Common Pitfalls
One common mistake is confusing “hypothesis” with “theory,” given their frequent usage across similar contexts. However, the critical difference lies in evidence support: a hypothesis is an initial idea or suggestion, whereas a theory is thoroughly vetted and supported by empirical data. Additionally, “speculation” can be mistaken for more credible forms of conjecture due to its casual tone.
Final Recap
To summarize:
- Hypothesis is best used when describing an initial proposal awaiting evidence.
- Conjecture, supposition, speculation, and proposition offer varying degrees of uncertainty, with “conjecture” being the most formal and speculative among them.
- Theory represents a more advanced stage than a hypothesis, characterized by solid supporting data.
