fickle and volatile
The adjectives fickle and volatile are often confused and sometimes used incorrectly. Volatile refers to the ability to fly, or in the case of Chemistry, it is the attribute that indicates the ease of evaporation of some liquid (such as alcohol, for example). On the other hand, fickle indicates the ability to turn or change direction. Nevertheless, fickle and volatile are considered synonymous, when used figuratively, to convey the notion of inconstancy and instability.
