Spontaneous Nasalization
Summary
This brief miscellany addresses the idea of ‘spontaneous nasalisation’ in historical linguistics. The author argues that when philologists describe a change as spontaneous they often disguise their ignorance of its causes. Nasalisation, the change of a pure vowel into a nasalised vowel, is rarely random. In most cases it arises through assimilation: a vowel may take on nasality from a following nasal consonant, from a preceding nasal vowel, or from an anusvāra. The article cites examples from Pali manuscripts where scribes pronounced vowels with a nasal twang, leading to spellings that scholars later misinterpreted as evidence of independent phonetic change. It emphasises that one must distinguish between genuinely conditioned nasalisation and the erroneous notion of spontaneous change. By identifying the specific phonetic environment in which nasalisation occurs, linguists can avoid misclassifying changes as mysterious or arbitrary. The piece also reminds readers that orthographic conventions sometimes preserve archaic pronunciations long after spoken forms have shifted. In sum, the author calls for greater methodological rigour in phonetic history, warning that terms like ‘spontaneous’ should not be used to mask gaps in knowledge.

Conclusion
The note concludes that so‑called spontaneous nasalisation is largely a misnomer. Most nasal vowels arise through identifiable processes of assimilation, and linguists should search for those causes rather than assume unpredictable change. Recognising the specific contexts in which nasalisation occurs leads to more accurate reconstructions of phonetic history.
