Did you know?

When Edgar Allan Poe spoke of an "efflorescence of language" in The Poetic Principle, he was referring to language that was flowery, or overly rich and colorful. This ties in to the garden roots of efflorescence, a word, like "flourish," that comes from the Latin word for "flower." More commonly, however, "efflorescence" refers to the literal or figurative act of blossoming much like a flower does. You could speak of "the efflorescence of nature in springtime," for example, or "the efflorescence of culture during the Renaissance." "Efflorescence" is also used in chemistry to refer to a process that occurs when something changes to a powder from loss of water of crystallization.
