Why “monostich” is a great word
MONOSTICH — [Noun & Adjective] A poem, or stanza, consisting of a single line; as an adjective, describing such a verse. From the Ancient Greek μόνος (mónos, "alone, single") + στίχος (stíkhos, "line"). First attested in English 1570–80, from Late Latin monostichum, from Greek monóstichon. Unlike a couplet, which builds meaning through a balanced pair, or a stich, which is merely a unit within a longer work, a monostich is a self-sufficient, solitary edifice. It is the lone cypress etched against a winter sky, the single perfect sentence spoken into an empty room, or the final, tolling bell that contains its entire history of sound—a universe of meaning where the silence around the line is part of the poem.
