Have you always had this leaning toward wanting to know about words and their etymologies? Maybe you even have a propensity to use the featured word several times in the course of the day—due, of course, not to a proclivity for pretentiousness, but because you simply have a penchant for using a rich vocabulary. And perhaps you have a predilection for using lots of synonyms, such as proclivity (from clivus, the Latin word for "slope"), referring to a tendency usually toward something bad; propensity, suggesting an often uncontrollable inclination; penchant, meaning an irresistible attraction; and predilection, which describes a strong liking derived from one's temperament.
