In some dialects, the distinction between /l/, /r/ and /n/ is neutralized to /n/ in word-final position, as in putan 'rope' (putal in most dialects).[3]
The central vowel [ə] is restricted to certain dialects.
In final position, there is a phonemic distinction between long and short vowels, e.g. /ikuː/ 'tail' vs. /siku/ 'elbow'.[3]
