Contrastive distribution occurs when two sounds placed in the same context produce different meanings. This is the case in the sounds [k] and [x] . For example: [kano] 'do' versus [xano] 'lose'.
The same happens with the sounds [ç] and [c]. They are in constrastive distribution as in shown in the following example: [çino] 'pour' versus [cino] 'move
In complementary distribution, where one sound occurs the other cannot. This is the case in the sounds [k] and [c] The first sound (palatal stop) appears before front vowels whereas the second sound (velar stop) appears elsewhere.
The sounds [ç] and [x] are also in complementary distribution. As in the previous example, the palatal appears before front vowels and the velar appears elsewhere
