Affixes

1. Definition
An affix is a formative attached to a stem. Affixes, like stems, are parts of the grammatical word (i.e. they are parts of the syntactic X0). Affixes need stems as their grammatical hosts, they necessarily cooccur with stems.

Affixes, unlike clitics, are categorially restrictive, i.e. they attach only to stems of a certain parts of speech. (English affix re- attaches only to verbs: re-use, but not numerals: *re-five.)

Affixes usually have a more restricted phonology, segments used for affixes in a language are only a subpart of the phoneme system. Affixes are usually shorter than stems, are phonologically bound, have more abstract meaning than stems and occur in a fixed order (but see counterexamples below).

Many simple morphemes are exclusively segmental and consist of a single affix. Therefore in a simplified view affixes are said to bear meanings, instead of saying it&rsquo;s the morphemes which bear meaning. For an affix which is a part complex morpheme, this view is somewhat misleading. For such examples see simulfix, morpheme or formative.

English (West-Germanic, Indo-European)

Akkadian (East-Semitic, Afroasiatic)

3.1. Position
Affixes vary in their position relative to the stem: prefix (precedes the stem), suffix (follows the stem), infix (is in the stem). All three types can be seen in the examples above, but here is a general scheme:

3.2. Inter-Affix Dependencies
Various dependencies can be found between affixes. One affix may change the meaning of another affix:

German (West-Germanic, Indo-European)

The occurrence of an affix may depend on another affix (coocurrence dependency):

Czech (West-Slavic, Indo-European)

A prefix and a suffix which only occur together are called a circumfix. The Czech and German examples above are not circumfixes in a proper sense. For details see circumfix.

Phonologically bound affixes
All of the above examples were affixes that are phonologically bound, i.e. they are a part of a phonological word. A Turkish example from Bickel & Nichols (in press) shall demonstrate this once again. (All vowels within the domain of a Turkish phonological word harmonize.):

tan-ış-tır-ıl-a-ma-dık-lar-ın-dan-dır

know-RECIP-CAUS-PASS-POT-NEG-NZR-PL-3POSS-ABL-3COP

‘It is because they cannot be introduced to each other.’

(lit. ‘[it] is from their not being able to be made known to each other.’)

Phonologically free affixes
Affixes need not be necessarily phonologically bound but can be phonological words of their own. What makes them affixes is being a syntactically unseparable part of the X0. The following Lai Chin sentence consists of one grammatical word having three affixes, but phonologically, it is three words. Nhaa and làay are phonologically free suffixes, whereas na- is a phonologically bound prefix.

Lai Chin (Example from Bickel & Nichols (in press))

Even English has some phonologically free words which can be analyzed as infixes (Examples from Bauer 1983):

[gw (ω kanga)<(ω bloody)>(ω roo)]

[gw (ω guaran)<(ω friggin)>(ω tee)]

Detached affixes
Detached affixes are phonologically bound, but their phonological host is not part of their grammatical host. A Santali example (taken from Neukom 2001:100) shall illustrate this:

The Santali verbal prefixes for subject agreement are phonologically bound to any phonological word that immediately precedes the verb. In cases where the intonational phrase begins with a verb, these subject agreement markers appear as the last suffix on that very verb form. For details see Neukom (2001: 113ff).

Lexical affixes
Affixes usually have more abstract meaning than stems. However, in Nuu-chah-nulth we find affixes with very concrete meaning, called lexical affixes:

Nuu-chah-nulth (Nootka), (Wakashan), (Nakayama 1997:38)

Nuu-cha-nulth (Nootka), (Wakashan), (Nakayama 1997:43)

Free order of affixes
In Kusunda (a language isolate of Nepal), at least some verbal suffixes may appear in random order (Watters 2005:70):

is in free variation with:

In Chintang, a Kiranti language of Nepal, we find a random order of prefixes (Bickel et al., Ms.):

is in free variation with:
