japanese words have traditionally been analysed as composed of moras; a distinct concept from that of syllables. each mora occupies one rhythmic unit, i.e. it is perceived to have the same time value. a mora may be "regular" consisting of just a vowel (v) or a consonant and a vowel (cv), or may be one of two "special" moras, and . a glide may precede the vowel in "regular" moras (cjv). some analyses posit a third "special" mora, , the second part of a long vowel (a chroneme). in this table, the period represents a mora break, rather than the conventional syllable break.
