There is a strong tendency for hendecasyllabic lines to end with feminine rhymes (causing the total number of syllables to be eleven, hence the name), but ten-syllable lines (""Ciò che 'n grembo a Benaco star non può"") and twelve-syllable lines (""Ergasto mio, perché solingo e tacito"") are encountered as well. Lines of ten or twelve syllables are more common in rhymed verse; "versi sciolti", which rely more heavily on a pleasant rhythm for effect, tend toward a stricter eleven-syllable format. As a novelty, lines longer than twelve syllables can be created by the use of certain verb forms and affixed enclitic pronouns (""Ottima è l'acqua; ma le piante abbeverinosene."").
