What does propension mean?
Propension means a natural, habitual, or strongly held inclination toward a particular kind of behaviour, attitude, or outcome. It is especially useful when describing a tendency that repeatedly directs someone's actions without necessarily making those actions inevitable. The word can be neutral: someone may have a propension toward careful planning, outdoor activity, or intellectual curiosity. More often, however, it appears in formal or evaluative contexts involving undesirable tendencies, such as a propension to exaggerate, manipulate, or act selfishly. Propensity is its more familiar synonym, but propension tends to have a somewhat more formal and faintly critical tone. In careful writing, the distinction can be useful: propensity is often preferred for an established general tendency, while propension may suggest a conspicuous or morally coloured inclination. The word is most natural in formal prose, professional analysis, and psychological or behavioural description.

Where does propension come from?
Propension comes from Latin propensio, meaning an inclination or leaning, derived from propensus, “leaning forward,” with the prefix pro- indicating forwardness. The underlying verb propendere combined pro- with pendere, “to hang” or “suspend.” English borrowed the noun in the early 17th century, and related forms include propensity and the adjective propense.
