Trocaie, also known as "trochaic meter," is a poetic foot consisting of two syllables, where the first syllable is stressed and the second is unstressed (notated as / u). It creates a rhythmic pattern that can evoke a sense of forward momentum and energy in poetry. Trochaic meter is often used in various forms of verse, including children's poetry and folk songs, due to its lively and engaging sound. Examples of trochaic words include "apple" and "table."
