Did You Know?

When it comes to synonyms of "propensity," the letter "p" predominates. "Proclivity," "preference," "penchant," and "predilection" all share with "propensity" the essential meaning "a strong instinct or liking." Not every word that is similar in meaning to "propensity" begins with "p," however. "Propensity" comes from Latin propensus, the past participle of "propendēre," a verb meaning "to incline" or "to hang forward or down." Thus "leaning" and "inclination" are as good synonyms of "propensity" as any of those "p"-words.

Origin of propensity
