In a relative clause, the verb has the suffix -tle (or -le if the final syllable contains /tl/) added to it. The order of the words in relative clauses remains the same as in regular clauses. The use of participles in Kala is rather different than in English and at first sight is difficult to understand. This is mainly due to the fact that the relative pronouns who, what, which, where are not used in Kala as in English.
yalapa to be able to walk produces: yalapatle who/which/that can walk
yalapak not to be able to walk produces: yalapanketle who/which/that can’t walk
This nominalizes the verb in some cases, and makes it possible for it to be either the subject or the object.

1sg O man for eat-time come-REL know

ke naka patlole pako
O woman sweep-REL young

The relative suffix is most often in the final position. In some cases, it may be followed by the negative -k.
