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
Syllabic verse in one verse tradition will typically not fit in another. Humans can perceive the number of members in a small set without actually counting them or mentally breaking them into subsets; the upper limit of this ability is estimated at between 5 and 9 units, and this seems to hold true in sequences of audible stimuli (e.g. syllables in a line of verse); so it is no surprise that syllabic hemistichs tend to be very short (typically 4 to 8 syllables), and to be grouped — and therefore separated from their neighbors — by markers such as stress, word boundary,
