 A syllable-final position cannot be more than one consonant (one of n, r, l, s or z) in most (or all) dialects in colloquial speech, reflecting Vulgar Latin background.Realizations like , , , , , , and are very common, and in many cases, they are considered acceptable even in formal speech.In general, the ten-vowel system of Classical Latin, which relied on phonemic vowel length, was newly modelled into one in which vowel length distinctions lost phonemic importance, and qualitative distinctions of height became more prominent.
