You'll Like the Etymology of Propensity

When it comes to synonyms of propensity, the letter "p" predominates. Proclivity, preference, penchant, and predilection all share with propensity the essential meaning of "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.
