monometro

Monometer is a term used in prosody to describe a line of verse that consists of a single metrical foot. The word derives from Greek monos meaning “one” and metron meaning “measure.” In practice, a monometer line contains only one foot—often iambic or trochaic—resulting in a very short line that may have two syllables (for a two-syllable foot) or three syllables (for certain three-syllable feet like dactyl or anapest). Because of its extreme brevity, monometer lines tend to produce a compact or abrupt cadence and are most commonly encountered in specialized or experimental poetic contexts rather than in ordinary verse.

Usage and context in poetry are generally limited. The concept is discussed in studies of classical and modern prosody, where scholars analyze how different feet behave when confined to a single measure in a line. Monometer is far less common than longer metrical forms such as dimeter or trimeter, and poets who work with it typically do so for epigrammatic effect, satire, or experimental constraint. When used, it emphasizes brevity, immediacy, and a pointed or abrupt tonal quality.

In scholarly terms, monometer is primarily of interest as a theoretical and analytical concept within versification. It serves to illustrate how versified lines can be constructed from a single foot and how such economy of form affects rhythm, stress, and meaning. Related topics include meter, different metrical feet (iamb, trochee, anapest, dactyl, etc.), and the broader study of versification. See also: meter and prosody.
