The key element in Navajo is the
verb. Verbs are composed of an abstract
stem to which
inflectional or
derivational prefixes are added. Every verb must have at least one prefix. The prefixes are affixed to the verb in a specified order. The Navajo verb can be sectioned into different components. The verb
stem is composed of an abstract
root and an often fused suffix. The stem together with a "classifier" prefix (and sometimes other thematic prefixes) make up the verb
theme. The thematic prefixes are prefixes that are non-
productive, have limited derivational function, and no longer have a clearly defined meaning. Examples of thematic prefixes include the archaic '
prefix, which only occurs on the verb stem meaning "to talk" as in ' "he's talking". The
theme is then combined with derivational prefixes that in turn make up the verb
base. Finally, inflectional prefixes (which Young & Morgan call "paradigmatic prefixes") are affixed to the
base – producing a complete Navajo verb.
Verb template The prefixes that occur on a Navajo verb are added in specified more or less rigid order according to prefix type. This type of morphology is called a
position class template (or
slot-and-filler template). Below is a table of a recent proposal of the Navajo verb template (Young & Morgan 1987). A given verb does not have a prefix for every position. In fact, most Navajo verbs are not as complex as the template might suggest: the maximum number of prefixes is around eight. The Navajo verb is composed of a verb stem and a set of prefixes. The prefixes can be divided into a conjunct prefix set and disjunct prefix set. The disjunct prefixes occur on the outer left edge of the verb. The conjunct prefixes occur after the disjunct prefixes, closer to the verb stem. Two types of prefixes can be distinguished by their different phonological behavior. : The prefix complex may be subdivided into 11 positions, with some of the positions having even further subdivisions: Although prefixes are generally found in a specific position, some prefixes change order by the process of
metathesis. For example, prefix '
(3i object pronoun) usually occurs before ', as in: : '''''' [ ← ] :: "I'm starting to drive some kind of wheeled vehicle along" However, when '
occurs with the prefixes and , the metathesizes with , leading to an order of ', as in: : '''''' [ ← ] :: "I'm in the act of driving some vehicle (into something) & getting stuck" instead of the expected *'
() ( is reduced to '). Although the verb template model of analysis has been traditionally used to describe the Navajo verb, other analyses have been proposed by Athabascanists.
Pronominal inflection Navajo verbs have
pronominal (i.e. pronoun) prefixes that mark both
subjects and
objects. The prefixes can vary in certain modes, particularly the perfective mode (See
Modes section below for a discussion of modes). The prefixes are
inflected according to
person and
number. The basic subject prefixes (and their abbreviations as used by Young & Morgan) are listed in the table below: : The subject prefixes occur in two different positions. The first and second subject prefixes (
-sh-,
-Vd-,
ni-,
-oh-) occur in position 8 directly before the classifier prefixes. The fourth, indefinite, and "space" subject prefixes (
ji-,
ʼa-,
ha-~ho-) are known as "deictic subject pronouns" and occur in position 5. The third person subject is marked by the absence of a prefix, which is usually indicated with a zero prefix
-∅- in position 8. The object prefixes can occur in position 4 as direct objects, in position 1a as "null postpositions", or in position 0 as the object of postpositions that have been incorporated into the verb complex. The
fourth person subject prefix
ji- is a kind of
obviative third person. It refers primarily to persons or personified animals (unlike the regular third person). It has a number of uses including: • referring to the main character in narratives • distinguishing between two third person
referents • referring politely or impersonally to certain socially-distant individuals (e.g. when speaking to opposite-sex siblings and relatives through marriage, giving admonitions, speaking of the dead) When used as an impersonal, it may be translated into English as "one" as in '''''' "one can cut one's hand playing with knives". The "space" prefix can be translated as "area, place, space, impersonal it" as in '
"the area/place is white" and "it is raining". The prefix has two forms: and with having derived forms such as and '. An example paradigm for "to freeze" (imperfective mode) showing the subject prefixes: :
Classifiers (transitivity prefixes) The "classifiers" are prefixes of position 9 (the closest to the verb stem) that affect the
transitivity of the verb, in that they are
valence and
voice markers. Calling them "classifiers" is a misnomer, however, as they do not classify anything and are not related to the classificatory verb stems (which actually do classify nouns; see
classificatory verbs below). There are four classifiers: } Some verbs can occur with all four classifier prefixes: • '
"it (a roundish object) lies in position" (') • '
"it (a roundish object) was taken up & out (i.e. extracted)" (') • '
"I keep a roundish object in position" (') • '
"I have my head in position" (') In other verbs, the classifiers do not mark transitivity and are considered thematic prefixes that simply are required to occur with certain verb stems. ==Modes, aspects and tenses==
