Tetun is spoken on the island of Timor around
Dili and in two separate areas to the east and west.
Morris (1984) is a linguistically unsophisticated source
with some especially confusing remarks about vowel
sequences. More sequences occur in the dictionary than are
listed in the introduction; probably all pairs of vowels
occur. /w/ might be analyzed as a prevocalic variant of
/u/, as Morris proposes, but there is no parallel to this
with /i/. Stress is normally penultimate except a few
items stressed on the final syllable.
