For my phonology homework, we're given the nasals [n] [m] [η] and nasalized glides [w] and [j]. From the data, I've found that [n] and [m] are phonemes and [η] is an allophone of /n/. What I can't figure out is where the nasal glides fit in. They appear w̃ and ȷ̃.

The exact question is this:

Look at the data. What phonetic contexts do w̃ and ȷ̃ appear in? They only appear before w and j, right? What does that tell you? – snail plane Mar 5 '14 at 4:31

To summarize, the nasalized glides w̃ and ȷ̃ are cases where ん or N (the Japanese syllable-final moraic nasal sound/uvular nasal) comes before /w/ and /j/ approximants, or in other words, the w or y-sounds. Observe these: (koNya with ȷ̃) こや, (yaNwari with w̃) やわり, (kaNyo with ȷ̃) かよ.

In general, where the ん or N comes before /j/ and /w/, the N nasalizes stuff. This answer's pretty simple though. Please add on or correct as needed!
