In linguistics, an affix is a morpheme that is attached to a word stem to form a new word or word form. Affixes may be derivational, like English -ness and pre-, or inflectional, like English plural -s and past tense -ed. They are bound morphemes by definition; prefixes and suffixes may be separable affixes. Affixation is the linguistic process that speakers use to form different words by adding morphemes at the beginning (prefixation), the middle (infixation) or the end (suffixation) of words.
Affixes are divided into many categories, depending on their position with reference to the stem. Prefix and suffix are extremely common terms. Infix and circumfix are less so, as they are not important in European languages. The other terms are uncommon.
|Prefix||un-do||prefix-stem||Appears before the stem|
|Prefixoid/semi-prefix/pseudo-prefix||flexi-cover||prefixoid-stem||Appears before the stem, but is only partially bound to it|
|Suffix /postfix||look-ing||stem-suffix||Appears after the stem|
|Suffixoid /semi-suffix /pseudo-suffix||cat-like||stem-suffixoid||Appears after the stem, but is only partially bound to it|
|Infix||Abso⟨bloody⟩lutely (tmesis)||st⟨infix⟩em||Appears within a stem — common e.g. in Austronesian languages|
|Circumfix||en⟩light⟨en||circumfix⟩stem⟨circumfix||One portion appears before the stem, the other after|
|Interfix||speed-o-meter||stema-interfix-stemb||Links two stems together in a compound|
|Duplifix||money~shmoney (shm-reduplication)||stem~duplifix||Incorporates a reduplicated portion of a stem|
(may occur before, after, or within the stem)
|Transfix|| Maltese: k⟨i⟩t⟨e⟩b "he wrote"|
(compare root ktb "write")
|s⟨transfix⟩te⟨transfix⟩m||A discontinuous affix that interleaves within a discontinuous stem|
|Simulfix||mouse → mice||stem\simulfix||Changes a segment of a stem|
|stem\suprafix||Changes a suprasegmental feature of a stem|
|Disfix|| Alabama: tipli "break up"|
(compare root tipasli "break")
|st⟩disfix⟨em||The elision of a portion of a stem|
Prefix and suffix may be subsumed under the term adfix, in contrast to infix.
When marking text for interlinear glossing, as in the third column in the chart above, simple affixes such as prefixes and suffixes are separated from the stem with hyphens. Affixes which disrupt the stem, or which themselves are discontinuous, are often marked off with angle brackets. Reduplication is often shown with a tilde. Affixes which cannot be segmented are marked with a back slash.
Lexical affixes (or semantic affixes) are bound elements that appear as affixes, but function as incorporated nouns within verbs and as elements of nouns. In other words, they are similar to word roots/stems in function but similar to affixes in form. Although similar to incorporated nouns, lexical affixes differ in that they never occur as freestanding nouns, i.e. they always appear as affixes.
Lexical affixes are relatively rare. The Wakashan, Salishan, and Chimakuan languages all have lexical suffixes — the presence of these is an areal feature of the Pacific Northwest of North America.
The lexical suffixes of these languages often show little to no resemblance to free nouns with similar meanings. Compare the lexical suffixes and free nouns of Northern Straits Saanich written in the Saanich orthography and in Americanist notation:
|-sen||-sən||"foot, lower leg"||sxene,||sx̣ənəʔ||"foot, lower leg"|
|-áwtw̱||-ew̕txʷ||"building, house, campsite"||, á,leṉ||ʔeʔləŋ||"house"|
Lexical suffixes, when compared with free nouns, often have a more generic or general meaning. For instance, one of these languages may have a lexical suffix that means water in a general sense, but it may not have any noun equivalent referring to water in general and instead have several nouns with a more specific meaning (such "saltwater", "whitewater", etc.). In other cases, the lexical suffixes have become grammaticalized to various degrees.
Some linguists have claimed that these lexical suffixes provide only adverbial or adjectival notions to verbs. Other linguists disagree arguing that they may additionally be syntactic arguments just as free nouns are and, thus, equating lexical suffixes with incorporated nouns. Gerdts (2003) gives examples of lexical suffixes in the Halkomelem language (the word order here is verb–subject–object):
|(1)||niʔ||šak’ʷ-ət-əs||łə słeniʔ||łə qeq|
|"the woman washed the baby"|
|"the woman baby-washed"|
In sentence (1), the verb "wash" is šak’ʷətəs where šak’ʷ- is the root and -ət and -əs are inflectional suffixes. The subject "the woman" is łə słeniʔ and the object "the baby" is łə qeq. In this sentence, "the baby" is a free noun. (The niʔ here is an auxiliary, which can be ignored for explanatory purposes.)
In sentence (2), "baby" does not appear as a free noun. Instead it appears as the lexical suffix -əyəł which is affixed to the verb root šk’ʷ- (which has changed slightly in pronunciation, but this can also be ignored here). Note how the lexical suffix is neither "the baby" (definite) nor "a baby" (indefinite); such referential changes are routine with incorporated nouns.
In orthography, the terms for affixes may be used for the smaller elements of conjunct characters. For example, Maya glyphs are generally compounds of a main sign and smaller affixes joined at its margins. These are called prefixes, superfixes, postfixes, and subfixes according to their position to the left, on top, to the right, or at the bottom of the main glyph. A small glyph placed inside another is called an infix.Similar terminology is found with the conjunct consonants of the Indic alphabets. For example, the Tibetan alphabet utilizes prefix, suffix, superfix, and subfix consonant letters.
A morpheme is the smallest meaningful unit in a language. A morpheme is not necessarily the same as a word. The main difference between a morpheme and a word is that a morpheme sometimes does not stand alone, but a word, by definition, always stands alone. The field of linguistic study dedicated to morphemes is called morphology.
In linguistics, morphology is the study of words, how they are formed, and their relationship to other words in the same language. It analyzes the structure of words and parts of words such as stems, root words, prefixes, and suffixes. Morphology also looks at parts of speech, intonation and stress, and the ways context can change a word's pronunciation and meaning. Morphology differs from morphological typology, which is the classification of languages based on their use of words, and lexicology, which is the study of words and how they make up a language's vocabulary.
A prefix is an affix which is placed before the stem of a word. Adding it to the beginning of one word changes it into another word. For example, when the prefix un- is added to the word happy, it creates the word unhappy. Particularly in the study of languages, a prefix is also called a preformative, because it alters the form of the words to which it is affixed.
Morphological derivation, in linguistics, is the process of forming a new word from an existing word, often by adding a prefix or suffix, such as un- or -ness. For example, unhappy and happiness derive from the root word happy.
An infix is an affix inserted inside a word stem. It contrasts with adfix, a rare term for an affix attached to the outside of a stem such as a prefix or suffix.
The Salishan languages are a group of languages of the Pacific Northwest in North America. They are characterised by agglutinativity and syllabic consonants. For instance the Nuxalk word clhp’xwlhtlhplhhskwts’, meaning "he had had [in his possession] a bunchberry plant", has thirteen obstruent consonants in a row with no phonetic or phonemic vowels. The Salishan languages are a geographically contiguous block, with the exception of the Nuxalk, in the Central Coast of British Columbia, and the extinct Tillamook language, to the south on the central coast of Oregon.
In morphology, a null morpheme or zero morpheme is a morpheme that has no phonetic form. In simpler terms, a null morpheme is an "invisible" affix. It is a concept useful for analysis, by contrasting null morphemes with alternatives that do have some phonetic realization. The null morpheme is represented as either the figure zero (0) or the empty set symbol ∅.
Crow is a Missouri Valley Siouan language spoken primarily by the Crow Nation in present-day southeastern Montana. The word, Apsáalooke, translates to "children of the large beaked bird." It is one of the larger populations of American Indian languages with 2,480 speakers according to the 1990 US Census.
In linguistics, a stem is a part of a word responsible for its lexical meaning. The term is used with slightly different meanings and would depend on the morphology of the language in question. In Athabaskan linguistics, for example, a verb stem is a root that cannot appear on its own, and that carries the tone of the word. Athabaskan verbs typically have two stems in this analysis, each preceded by prefixes.
Halkomelem is a language of various First Nations peoples of the Pacific Northwest Coast. It is spoken in what is now British Columbia, ranging from southeastern Vancouver Island from the west shore of Saanich Inlet northward beyond Gabriola Island and Nanaimo to Nanoose Bay and including the Lower Mainland from the Fraser River Delta upriver to Harrison Lake and the lower boundary of the Fraser Canyon.
Klallam,Clallam, Ns'Klallam or S'klallam, now extinct, was a Straits Salishan language that was traditionally spoken by the Klallam peoples at Becher Bay on Vancouver Island in British Columbia and across the Strait of Juan de Fuca on the north coast of the Olympic Peninsula in Washington.
The Tonkawa language was spoken in Oklahoma, Texas, and New Mexico by the Tonkawa people. A language isolate, with no known related languages, Tonkawa has not had L1 speakers since the mid 1900s. Most Tonkawa people now only speak English.
The Kutenai language, also Kootenai, Kootenay, Ktunaxa, and Ksanka, is the native language of the Kutenai people of Montana and Idaho in the United States and British Columbia in Canada. It is typically considered a language isolate, unrelated to the Salishan family of languages spoken by neighboring tribes on the coast and in the interior Plateau. The Kutenai also speak ʔa·qanⱡiⱡⱡitnam, Ktunaxa Sign Language.
Comox or Éy7á7juuthem is a Coast Salish language historically spoken in the northern Georgia Strait region, spanning the east coast of Vancouver Island and the northern Sunshine Coast and adjoining inlets and islands. More specifically, ʔayajuθəm was traditionally spoken in Bute Inlet, in Squirrel Cove, and in Sliammon, located in the area now known as Powell River.
In linguistics, a suffix is an affix which is placed after the stem of a word. Common examples are case endings, which indicate the grammatical case of nouns, adjectives, and verb endings, which form the conjugation of verbs. An inflectional suffix is sometimes called a desinence or a grammatical suffix or ending. Inflection changes the grammatical properties of a word within its syntactic category. Derivational suffixes can be divided into two categories: class-changing derivation and class-maintaining derivation.
Austronesian alignment, also known as the Philippine-type voice system or Austronesian focus system, is a typologically unusual kind of morphosyntactic alignment in which "one argument can be marked as having a special relationship to the verb". This special relationship manifests itself as a voice affix on the verb that corresponds to a noun within the same clause that is either marked for a particular grammatical case or found in a privileged structural position within the clause or both.
English prefixes are affixes that are added before either simple roots or complex bases consisting of (a) a root and other affixes, (b) multiple roots, or (c) multiple roots and other affixes. Examples of these follow:

Mehek is a Tama language spoken by about 6300 people in a somewhat mountainous area along the southern base of the Torricelli Mountains in northwestern Papua New Guinea. Mehek is spoken in six villages of Sandaun Province: Nuku, Yiminum, Mansuku, Yifkindu, Wilwil, and Kafle. Mehek is most closely related to Pahi, with 51% lexical similarity, and spoken approximately 20 kilometers to the southwest. Mehek is a fairly typical Papuan language, being verb-final, having a relatively simple phonology, and agglutinative morphology. There is very little published information about Mehek. The literacy rate in Tok Pisin, spoken by nearly everyone, is 50-75%. Mehek is not written, so there is no literacy in Mehek. Tok Pisin is primarily used in the schools, with 50% children attending. There is also a sign language used by the large number of deaf people in the Mehek community.
