Word Origin

Latin, late 18th century

Why this word?

The Latin root “florescere” means “begin to bloom”; however, “effloresce” is not usually referring to literal blooming flowers. It’s usually used in a figurative description of something coming into maturity or peak performance. When using the alternate definition of “effloresce,” it has a specific chemical usage. When a substance effloresces upon contact with the air, it loses moisture and turns into a fine powder. The word can also be used to describe rocks or brickwork with a salt content that crystallizes on the surface.
