The Western Apache language is a Southern Athabaskan language spoken among the 14,000 Western Apaches in Mexico in the states of Sonora and Chihuahua and in east-central Arizona. There are approximately 6,000 speakers living on the San Carlos Reservation and 7,000 living on the Fort Apache Reservation.^[2] In Mexico, they mainly live in Hermosillo, Sonora, and other native communities in Chihuahua.^[3] Goodwin (1938) claims that Western Apache can be divided into five dialect groupings:

• Cibecue
• Northern Tonto
• Southern Tonto
• San Carlos
• White Mountain

Other researchers do not find any linguistic evidence for five groups but rather three main varieties with several subgroupings:

• San Carlos
• White Mountain
• Tonto

Western Apache is most closely related to other Southern Athabaskan languages like Navajo, Chiricahua Apache, Mescalero Apache, Lipan Apache, Plains Apache, and Jicarilla Apache.

In 2011, the San Carlos Apache Tribe's Language Preservation Program in Peridot, Arizona, began its outreach to the "14,000 tribal members residing within the districts of Bylas, Gilson Wash, Peridot and Seven Mile Wash",^[4] only 20% of whom still speak the language fluently.^[5]

Place names

Many Western Apache place names that are currently in use are believed to be creations of Apache ancestors.^[6] Keith Basso, a prominent Western Apache linguist, writes that the ancestors frequently traveled for food, and the need to remember specific places was "facilitated by the invention of hundreds of descriptive placenames that were intended to depict their referents in close and exact detail." Basso also writes that place names provide descriptions of specific locations and also "positions for viewing these locations." The place names are a fundamental aspect of Western Apache communication, allowing for what Basso describes as an appropriation of "mythic significance" for "specialized social ends" via the practice of "speaking with names."

Place names can be descriptive or commemorative or a means of identifying clans. Social groups will often use place names as a way to communicate. For example, they use place names to explain what happened to them: If there is a story linked to the location, they can relate to it or use it as a warning. This use of place names is known in the culture as "shooting with stories," as they shoot one another with stories like arrows of information.^[7]

Grammar

Western Apache uses a classificatory verb system comparable to both the Jicarilla and Mescalero Apaches. Basso gives this example: "the stems –tii and –'a are used in the phrases nato sentii and nato sen’a both of which may be translated broadly as "hand (me) the tobacco." The difference in meaning between the two verb forms is signaled by their stems:

• --tii refers to the handling of a single, elongated object (e.g., a cigarette)
• –‘a refers to the handling of a single, compact object (e.g., a packet of cigarettes).

In short, the referent of the noun nato ("tobacco") is made more precise according to the stem with which it is coupled."^[8]

The use of classificatory verbs is similar to that of nouns: the speaker must select an expression that corresponds to the situation in the world he wishes to refer to. The speaker must place specific objects into categories and use the appropriate verb form in accordance with the particular category. Basso gives these examples of classifications for the Western Apache verb system:

Animal/Non-animal

There are two features on this dimension: "animal" and "non-animal."

• The former, designated by the symbol (a1) includes all vertebrates and insects.
• The latter, designated (a2), includes flora, liquids, minerals, and practically all items of material culture.

Enclosure

There are two features on this dimension.

• The first (bl) refers to the condition whereby the item or object being talked about is enclosed in a container.
• The second (b2) refers to the condition whereby it is not enclosed, i.e., not in a container.

State

There are three features on this dimension:

"solid" (c1), "plastic" (c2), and "liquid" (c3).

The second feature refers to moist, plastic substances such as mud, wet clay, etc., and might also have been defined as "neither solid nor liquid."

Number

There are three features on this dimension:

"one" (d1), "two" (d2), and "more than two" (d3).

Rigidity

There are two features on this dimension:

"rigid" (e1), and "non-rigid" (e2).

The Apache consider an object to be rigid (nkliz) if, when held at its edge or end, it does not bend.

Length

There are two features on this dimension:

• The first (f1), refers to the condition whereby the horizontal length of an object is at least three times greater than either its width of height.
• The second feature (f2) refers to the condition whereby the length of an object is less than three times its width or height.

Portability

There are two features on this dimension:

"portable" (g1) and "non-portable" (g2).

• The former refers to items light enough in weight to be easily carried by one person.
• The latter refers to items sufficiently heavy to require at least two people to carry them.

Phonology

Consonants

There are 31 consonants in Western Apache:

		Bilabial	Alveolar			Palatal	Velar	Glottal
			plain	sibilant	lateral
Nasal		pronounced as /link/	pronounced as /link/
Stop	voiced		pronounced as /link/
	voiceless	pronounced as /link/	pronounced as /link/	pronounced as /link/	pronounced as /link/	pronounced as /link/	pronounced as /link/	pronounced as /link/
	aspirated		pronounced as /link/	pronounced as /link/	pronounced as /link/	pronounced as /link/	pronounced as /link/
	ejective		pronounced as /link/	pronounced as /link/	pronounced as /link/	pronounced as /link/	pronounced as /link/
Fricative	voiceless			pronounced as /link/	pronounced as /link/	pronounced as /link/	pronounced as /link/	pronounced as /link/
	voiced			pronounced as /link/		pronounced as /link/	pronounced as /link/
Approximant					pronounced as /link/	pronounced as /link/	pronounced as /link/

Western Apache utilizes unaffricated stops. Willem de Reuse explains, "Unaffricated stop consonants are produced in three locations: bilabial, alveolar, velar. At the alveolar and velar places of articulation, there are three possibilities: aspirated, ejective, and unaspirated. The voiceless unaspirated alveolars are characteristically realized as taps in intervocalic environments other than stem-initial position. The bilabial stops are more restricted. Ejective bilabial stops do not occur, and aspirated bilabial stops are rarely attested, surfacing primarily, if not exclusively, in borrowed words. The closure for three alveolar stops is voiceless, as indicated by the absence of any energy in the spectrograms during the closure phase."^[9]

Vowels

There are 16 vowels in Western Apache:

		Front		Central		Back
		short	long	short	long	short	long
	oral	pronounced as /ɪ/	pronounced as /iː/
	nasal	pronounced as /ɪ̃/	pronounced as /ĩː/
	oral	pronounced as /ɛ/	pronounced as /ɛː/			pronounced as /o /	pronounced as /oː/
	nasal	pronounced as /ɛ̃/	pronounced as /ɛ̃ː/			pronounced as /õ/	pronounced as /õː/
	oral			pronounced as /a/	pronounced as /aː/
	nasal			pronounced as /ã/	pronounced as /ãː/

An acute accent /á/ represents a high toned accent. Low toned accents are not marked.

Phonetic Semantic signs are divided into two sub-parts: a logographs^[10] (donate only one word) and phraseographs (donate one or more words).

Writing system

The only writing system native to Western Apache is a system of symbols created in 1904 by Silas John Edwards to record 62 prayers that he believed came to him from heaven.^[11] A Silas John prayer-text is a set of graphic symbols written on buckskin or paper. The symbols are arranged in horizontal lines which are read from left to right in descending order. Symbols are separated by a space, and each symbol corresponds to a single line of prayer, which may consist of a word, a phrase, or one or more sentences.^[11] An interesting feature of this writing system is that it includes symbols for nonverbal actions as well as verbal speech.^[11]

Symbols can either be "compound" or "non-compound". Compound symbols consist of two symbols being combined in order to form a new symbol. Non-compound symbols are symbols that are not combination of two separate symbols.^[11] The "names" of non-compound symbols are the same as the line of text that the symbols elicit. Because of this, the linguistic referent of a non-compound symbol is always the same as the meaning of the element that forms it and can be learned in a single operation.^[11]

Alphabet and pronunciation

Western Apache uses a modified version of the Latin alphabet:

Usage

The geographic locations of events are crucial components to any Western Apache story or narrative.^[6] All Western Apache narratives are spatially anchored to points upon the land, with precise depictions of specific locations, which is characteristic of many Native American languages.^{[10] [6]} Basso called the practice of focusing on places in the language "speaking with names."^[6]

According to Basso, the Western Apache practice of "speaking with names" expresses functional range and versatility. Basso claims that "a description of a place may be understood to accomplish all of the following actions:

1. produce a mental image of a particular geographical location;
2. evoke prior texts, such as historical tales and sagas;
3. affirm the value and validity of traditional moral precepts (i.e., ancestral wisdom);
4. display tactful and courteous attention to aspects of both positive and negative face;
5. convey sentiments of charitable concern and personal support;
6. offer practical advice for dealing with disturbing personal circumstances (i.e., apply ancestral wisdom);
7. transform distressing thoughts caused by excessive worry into more agreeable ones marked by optimism and hopefulness;
8. heal wounded spirits."^[6]

Basso also claims the practice of "speaking with names" can occur only between those with shared "knowledge of the same traditional narratives." He notes that though many elders in Western Apache communities, such as Cibecue, share this knowledge, younger generations of Western Apache "are ignorant of both placenames and traditional narratives in increasing numbers," which makes engaging in the practice of "speaking with names" incredibly difficult.

Examples

• Hat' ii baa nadaa? – What are you doing?/What are you busy with?^[12]
• Shiyoo' baa nashaa. – I am doing my beading.^[12]
• Doo shaa nadaa da. – Don't bother me.^[12]
• Naa naghaa. – S/he is bothering you^[12]

Revitalization efforts

Western Apache is an endangered language, and there are efforts to increase the number of speakers.^[12] One method of teaching Western Apache is the Total Physical Response (TPR) Method,^[12] which focuses, especially in early instruction, on commands.^[12] That method is best for teaching the straightforward aspects of grammar, such as yes-and-no questions, and can be enhanced with further grammatical exercises.^[12]
