direct or inverse form respectively. The following examples place the second person marker first linearly but the direct and inverse suffixes change the semantic roles. The direct marker /-i-/ in the sentence ki-wāpam-i-n indicates that it should be read "you see me". The reading is reversed to "I see you" in the sentence ki-wāpam-iti-n because of the inverse marker /-iti-/. Compare the difference in meaning between the two directions in the following tables. Note that the situation is made more complicated when both referents are third persons because Plains Cree implements obviation. For example, we have the sentence sēkihēw nāpēw atimwa. The verb sēkihēw "scare" contains the direct-set marker /-e:w-/, indicating that the proximate third person is acting on the obviative. The noun nāpēw "man" is marked as proximate through the absence of a suffix while the noun atimwa "dog" contains the obviative suffix /-wa/. Thus the sentence reads "the man scares the dog", with special emphasis on the proximate "man". This is contrasted by the sentence sēkihik nāpēw atimwa, where the markers for obviation are the same but the direction marker is now the inverse-set /-ik/ representing action of the obviative third person on the proximate third. Therefore, the sentence becomes "the dog scares the man" and the emphasis still lies with the proximate "man". Of course, the sentence may require that the dog atim be the proximate noun, in which case the sentence would be either sēkihēw nāpēwa atim "the dog (3) scares(3-(3')) the man (3')" or sēkihik nāpēwa atim "the man (3') scares ((3')-3) the dog (3)". Direction and obviation are not versions of the passive, which is formed separately in Plains Cree. Locative suffix Because Plains Cree does not have a true case marking system, it has to instead rely on direction, obviation, and the locative suffix. This suffix, /ehk/ or its variant /ena:hk/, has the basic meanings of at, in, on, etc. The simple locative suffix /ehk/ can be used with stems or possessed themes, such as the stem skāt "leg". The personal pronoun /ni-/ can be added to the stem to make niskāt "my leg" and the addition of the plural suffix /-a/ makes niskāta "my legs". On top of these changes, the simple locative suffix is affixed to produce niskātihk "on my leg(s)". The distributive locative suffix /ena:hk/ is used with nouns that reference humans or animals. In this way, ayīsiyiniw- "human being"
