At the ends of words, vowels may appear both long and nasalized. This occurs historically where there was a final nasal /m/ or /n/. Within words, rather than nasal vowels there are sequences of vowel plus nasal consonant which matches the articulation of the following consonant. Thus nasal vowels may be analyzed as /Vn/ or /VN/.
