Understanding “Plausible”: Definition, Synonyms, and Usage

Plausible – Definition and Part of Speech

The word plausible is an adjective used to describe something that appears reasonable or credible based on available evidence or arguments, though it might not be true or guaranteed. It often suggests a convincing argument that could be accepted as potentially correct until proven otherwise. As an adjective, it doesn’t have separate forms like verbs do, but its meaning can vary slightly depending on context.

Core Synonyms

Below is a table listing the main synonyms of plausible, along with their brief definitions, example sentences, and appropriate style or register:

Synonym Brief Definition/Nuance Example Sentence Style/Register
Credible Conveys reliability and trustworthiness “The witness provided a credible account of the event.” Formal/Academic
Convincing Suggests effectiveness in persuading “Her argument was so convincing that everyone agreed with her stance.” Business/Formal
Reasonable Implies soundness based on logic or fairness “The explanation was reasonable, given the circumstances.” Casual/Academic
Probable Indicates a likelihood based on available evidence “Given all factors, this outcome is probable.” Academic/Technical
Believable Suggests something that can be accepted as true “His story seemed believable enough to merit further investigation.” Informal/Casual

Usage Notes

  • Credible: Often used in formal settings such as academic writing or professional reports. It implies not only the possibility of truth but also trustworthiness and authority.

  • Convincing: Suitable for business presentations or persuasive essays where the objective is to sway opinion through effective argumentation.

  • Reasonable: Commonly used in both casual conversations and written discourse when discussing fairness, logic, or moderation. It carries a neutral tone that suggests balance.

  • Probable: Best suited for contexts involving predictions, statistics, or scenarios based on likelihoods—such as scientific papers or risk assessments.

  • Believable: Frequent in informal settings where the goal is to convey that something can be accepted without skepticism, often used in storytelling or casual discussions.

Common Pitfalls

One common confusion arises with plausible and probable. While both imply likelihood, plausible focuses more on how convincing an argument might appear, whereas probable suggests a higher statistical chance of occurrence. Another potential mix-up is between credible and believable, where the former implies trustworthiness and authority while the latter simply means something can be accepted as true.

Final Recap

The key synonyms for plausible include credible, convincing, reasonable, probable, and believable. Each synonym has its unique nuance:

  • Credible emphasizes trustworthiness.
  • Convincing focuses on persuasive power.
  • Reasonable denotes sound logic or fairness.
  • Probable indicates likelihood.
  • Believable suggests acceptability.
