1120: Vocalic Assimilation in Kalaallisut Jan 2, 2018

English has plenty of examples of assimilation: when a sound consistently changes due to the phonemic context, i.e. the sounds around (particularly after) it. This can be seen with [n], which becomes [m] before sounds like [p] (e.g. 'impossible' is the negating 'in-' prefix + 'possible), or [t] becoming [t͡ʃ] before [ɹ] (e.g. the sound modified from 'tail to 'trail'). In Kalaallisut (a.k.a. West Greenlandic) this is even more extreme. At first glance it may seem that there are between 5 and 11 vowels, but because of assimilation there are only 3 vocalic phonemes: [a], [i], and [u]. Funnily, the alphabet for Kalaallisut contains 5 vowels—A, E, I, O, and U—but E and O only appear before [R] and [q]. All of the other vowels are allophones of [i], [a] or [u], even though they would be considered separate phonemes in other languages such as English. To see the range of each of these Greenlandic vowels, look at this graph below (citation after the links).
