The noun 'die Plausibilität' (plausibility) belongs to this adjective. It describes the quality of being convincing or credible.

'Plausibel' (plausible) is very often used with verbs of perception or impression. Typical constructions are 'plausibel klingen' (to sound plausible), 'plausibel erscheinen' (to appear plausible), or 'plausibel wirken' (to seem plausible).
Ihre Argumentation klingt für mich nicht plausibel.
Her argument doesn't sound plausible to me.
The adjective often describes abstract nouns that express a justification or idea. Typical nouns are 'eine plausible Erklärung' (a plausible explanation), 'ein plausibler Grund' (a plausible reason), or 'ein plausibles Argument' (a plausible argument).
Für sein Fehlen nannte er einen plausiblen Grund.

The word belongs more to elevated or educated language. It is often used in discussions, formal texts, or when one wants to give a rational assessment.

conceivable
'denkbar' and 'plausibel' can both express that something does not seem impossible. The important difference is: 'denkbar' only means that you can imagine something as a possibility. 'plausibel' means that an explanation or statement sounds logical and credible. Learners may confuse the words because both have to do with possibility. But something can be 'denkbar' without already being 'plausibel'. 'plausibel' is especially used with reasons, explanations, and arguments.

Seine Erklärung für die Verspätung klingt plausibel.
His explanation for the delay sounds plausible.
Nach der Arbeit haben wir mehrere denkbare Lösungen für das Problem gesammelt.
