Remember This
Implausible is the opposite of plausible. The prefix im- negates the root word, which comes from the Latin plausibilis meaning worthy of applause; thus implausible literally means not worthy of belief or not credible.
Other Forms
Note
Use implausible to describe something that strains credibility but is not absolutely impossible. It is weaker than 'unbelievable' and should be chosen when there is doubt about believability rather than certainty of impossibility.
