Noun
prenasalization (countable and uncountable, plural prenasalizations)
The act of prenasalizing.
A few languages also have pre-glottalized nasal clicks, which have very brief prenasalization but have not been phonetically analyzed to the extent that other types of clicks have. Source: Internet
Note that the terms prenasalization and postnasalization are normally used only in languages where these sounds are phonemic: that is, not analyzed into sequences of stop plus nasal. Source: Internet
