Modern Hindi words such as [dãt] ‘tooth’ and [t ∫ãnd] ‘moon’ had similar phonetic structure in Middle Indo-Aryan, with conventional transliterations of danta and čanda, respectively. The development of the long nasal vowel is usually correlated with loss of the nasal consonant. If so, why does one form still contain a nasal consonant? We argue that a sequence of nasalized vowel + voiced stop (but not voiceless stop) can, for phonetic reasons, engender an epenthetic nasal, and we demonstrate that the same process can be found (nondistinctively) in present-day Hindi and French in the junction between a word-final nasal vowel and a following word-initital voiced stop. A nondistinctive epenthetic nasal can become a ‘full’ or ‘lexical’ nasal when listeners reinterpret this transitional event as purposeful or intended.
