Suffixes

The suffixes relevent to this chapter are:

Tag Form Form Description
-Ben w-ez w-ez Benefactive Applicative
-Cau y-em y-em Causative
-Man -ha -ha Mantenential
-Rfx -ci' -ci' Reflexive
-Aut -ci' -ci' Autocausative
-Per y-ak y-ak Perlative Applicative

Valence-Increasing Operations

Each of these adds one argument to the verb's argument structure, increasing its valence by one. Since a verb's valence is limited to three, the original verb can't be ditransitive. For each of these, the suffix (-Ben, -Cau, or -Man) is appended to the stem before any aspect marking.

Benefactive Applicative

This applicative is either benefactive or malefactive, depending on the word to which it's applied and on pragmatic factors. Hence the new argument, which must be animate, can refer to a beneficiary or to a maleficiary. The benefit (or its opposite) may be interpreted as occurring after the action in some cases.

Causative

The causative adds an animate argument whose referent functions as the cause of a situation. The act of causation may be interpreted as occurring prior to the situation.

It also makes a stative situation dynamic, so that the unmarked aspect is now treated as perfective and the imperfective suffix is now possible.

The causative can be applied to monovalent and relational verbs, producing transitive and trivalent verbs, respectively. It can also be applied to some static transitive verbs as well (also with trivalent verbs resulting). In all cases, the new argument is Argument-2.

Mantenential

The mantenential adds an animate argument whose referent functions to maintain a situation, the maintenance being concurrent with the situation.

It also makes a dynamic situation stative, so that the unmarked aspect is now treated as imperfective and the imperfective suffix is no longer possible.

With regard to application and argument structure, the mantenential acts like the causative.

Valence-Decreasing Operations

Since K'tlê  can effectively eliminate arguments by marking them as indefinite, there aren't any of the usual passives and antipassives. However, reflexive marking may be considered a valence-changing operation, in that the argument-structure is changed. Core argument incorporation also decreases the valence (see Deriving Verbs from Nouns).

Reflexive

The reflexive indicates that Argument-1 has the same referent as Argument-2, and is therefore limited to direct forms, which take the reflexive suffix {-ci'} |-ci'| (-Rfx) in place of Argument-1. All non-monovalent words can be marked as reflexive, although this is not very common for trivalent verbs and rare for relational verbs and possessed nouns. The argument-structure changes are:

Note that reflexives and intensives aren't identical: the latter use the normal non-reflexive forms with a personal pronoun.

Suffix Combinations

The reflexive can be used along with a valence-increasing operation, in some cases.

Other Operations

These neither increase nor decrease the number of arguments of a verb, but do affect the argument structure in some way.

Autocausative

Although it doesn't add any arguments, the autocausative does add a semantic role to an existing argument and in some cases, change the positions of the arguments. The autocausative can be used with patientive verbs, making them agentive, with relational verbs, making them transitive, and with transitive verbs denoting perception or mental states, which stay transitive.

The autocausative is marked with the suffix {-ci'} |-ci'| (-Aut); this is identical to the reflexive suffix (-Rfx) but occurs in a different position.

The autocausative also makes a stative situation dynamic, so that the unmarked aspect is now treated as perfective and the imperfective suffix following the autocausative suffix is now possible.

Perlative Applicative

The only effect this applicative has on the verb's argument structure is to replace an argument having a locative role with one having a perlative role (that is, the object now specifies a route instead of a location).

It derives a dynamic verb specifying a route from a stative verbs denoting a spatial relation or position by appending the perlative suffix {y-ak} |y-ak| (-Per) to the stem.

The perlative applicative and the benefactive applicative can both occur within the same word; the former suffix must appear first.
