This is one of the great phonetics/phonology divides. If you define a stop as complete blockage of airflow, then sounds such as [m, n] are clearly not stops. So why would someone want to redefine a stop by adding the qualification "in the oral cavity" to the condition "complete blockage of airflow"? Contrary to Christophe's assertion above, there are many languages which treat nasals and stops identically WRT to certain phonological processes. Let me give you a Shoshoni example (you had to know I'd get Shoshoni in the discussion somehow!) In Shoshoni, there are lenition processes which affect underlying voiceless stops and nasals. One of these alternates a voiceless stop with a voiced fricative in intervocalic position: [pia] 'mother' [nyBia] 'my mother' [kasa] 'wing' [nyGasa] 'my wing' And so on. This process also applies to nasals [m, n] to yield a nasalized [w] and a nasalized [y] or tap: [mo'o] 'hand' [nyw~o'o] 'my hand' [naiBi] 'girl' [nyr~aiBi] 'my girl' (nasalized [y~] only occurs following front vowels; nasalized tap occurs elsewhere).

Well, "nasal" implies only nasal airflow, with or without concomitant oral closure. There are nasal(ized) vowels, after all.

Yes. See the Shoshoni examples above. Although I would contend that the lenition of nasals in Shoshoni is as much a product of phonetics ("ease of articulation") as the corresponding lenition of voiceless stops.

Fula/Pulaar is reported as having a constrast between nasal-stop clusters and prenasalized stops. I don't know the arguments well enough to comment (but I will)--they seem to rest on duration of nasal airflow; the cluster has a longer period of nasal airflow than the prenasalized stop.

Only in medial position? Then what is your evidence that they are prenasalized stops rather than clusters? The most telling argument for prenasalized stops is if they can occur word-initially; otherwise, the jury's still out, unless you have other compelling evidence. Of course, it's your *created* language, and if you say that they are prenasalized stops, then who am I to argue? :-) Dirk -- Dirk Elzinga dirk.elzinga@m.cc.utah.edu
