Syllabic verse stress accent (as English does). This means that the French metric line is generally determined by the number of syllables. The most common metric lengths are the ten-syllable line ("décasyllabe"), the eight-syllable line ("octosyllabe") and the twelve-syllable line (the so-called "alexandrine"). Special syllable counting rules apply to French poetry. A silent or mute 'e' counts as a syllable before a consonant, but not before a vowel (where "h aspiré" counts as a consonant). When it falls at the end of a line, the mute "e" is hypermetrical (outside the count of syllables). Polish syllabic verse is similar to French. The

This loosening process eventually led to "vers libéré" and finally to "vers libre". In English verse, "alexandrine" is typically used to mean "iambic hexameter": Whereas the French alexandrine is syllabic, the English is accentual-syllabic; and the central caesura (a defining feature of the French) is not always rigidly preserved in English. Though English alexandrines have occasionally provided the sole metrical line for a poem, for example in lyric poems by Henry Howard, Earl of Surrey and Sir
