The History of Volatile Is for the Birds
Volatile was originally for the birds—quite literally. Back in the 14th century, the word was a noun and volatiles were birds (especially wild fowl) or other winged creatures, such as butterflies. That's not as flighty as it sounds. Volatile traces back to the Latin verb volare, which means “to fly.” By the end of the 16th century, people were using volatile as an adjective to describe meal ground so fine and light that it could easily “fly” or be blown about. Soon after, the adjective was extended to creatures that were capable of flying (as in “volatile insects”), later to vapors and gases, and by the early 17th century, to individuals or things as prone to sudden change as some gaseous substances. In recent years, volatile has alighted in economic, political, and technical contexts far flown from its avian origins.
