- Alternation (linguistics)
In
linguistics , an alternation is the phenomenon of aphoneme ormorpheme exhibiting variation in its phonological realization. Each of the various realizations is called an alternant. The variation may be conditioned by the phonological, morphological, and/or syntactic environment in which the morpheme finds itself.Alternations provide linguists with data that allow them to determine the
allophone s andallomorph s of a language's phonemes and morphemes and to develop analyses determining the distribution of those allophones and allomorphs.Phonologically conditioned alternation
An example of a phonologically conditioned alternation is the English
plural marker commonly spelled "s" or "es". [cite book |last=Cohn |first=Abigail |chapter=Phonology |pages=202–203 |title=The Handbook of Linguistics |editor=in Mark Aronoff and Janie Rees-Miller (eds.), |year=2001 |publisher=Blackwell Publishers |location=Oxford |isbn=0-631-20497-0] This morpheme is pronounced IPA| [s] , IPA| [z] , or IPA| [ɪz] , depending on the nature of the preceding sound.# If the preceding sound is a
sibilant consonant (one of IPA|/s/, /z/, /ʃ/, /ʒ/, /tʃ/, or IPA|/dʒ/), the plural marker takes the form IPA| [ɪz] . Examples:
#*"mass" IPA| [mæs] , plural "masses" IPA| [ˈmæsɪz]
#*"fez" IPA| [fɛz] , plural "fezzes" IPA| [ˈfɛzɪz]
#*"mesh" IPA| [mɛʃ] , plural "meshes" IPA| [ˈmɛʃɪz]
#*"mirage" IPA| [mɪˈrɑʒ] , plural "mirages" IPA| [mɪˈrɑʒɪz]
#*"church" IPA| [tʃɝtʃ] , plural "churches" IPA| [ˈtʃɝtʃɪz]
#*"bridge" IPA| [brɪdʒ] , plural "bridges" IPA| [ˈbrɪdʒɪz]
# Otherwise, if the preceding sound is voiceless, the plural marker takes the form IPA| [s] . Examples:
#*"mop" IPA| [mɑp] , plural "mops" IPA| [mɑps]
#*"mat" IPA| [mæt] , plural "mats" IPA| [mæts]
#*"pack" IPA| [pæk] , plural "packs" IPA| [pæks]
#*"cough" IPA| [kɔf] , plural "coughs" IPA| [kɔfs]
#*"myth" IPA| [mɪθ] , plural "myths" IPA| [mɪθs]
# Otherwise, the plural marker takes the form IPA| [z] .
#*"dog" IPA| [dɔg] , plural "dogs" IPA| [dɔgz]
#*"glove" IPA| [glʌv] , plural "gloves" IPA| [glʌvz]
#*"ram" IPA| [ræm] , plural "rams" IPA| [ræmz]
#*"doll" IPA| [dɑl] , plural "dolls" IPA| [dɑlz]
#*"toe" IPA| [toʊ] , plural "toes" IPA| [toʊz]Alternation related to meaning
Morphologically conditioned alternation
An example of a morphologically conditioned alternation is found in French, where many
adjective s have aconsonant at the end in the feminine gender that is missing in the masculine: [cite book |last=Steriade |first=Donca |year=1999 |chapter=Lexical conservatism in French adjectival liaison |editor=in Jean-Marc Authier, Barbara E.

*masculine "petit" IPA| [pəti] , feminine "petite" IPA| [pətit] "small"
*masculine "grand" IPA| [gʁɑ̃] , feminine "grande" IPA| [gʁɑ̃d] "big"
*masculine "gros" IPA| [gʁo] , feminine "grosse" IPA| [gʁos] "tall"

*masculine "franc" IPA| [fʁɑ̃] , feminine "franche" IPA| [fʁɑ̃ʃ] "sincere"
*masculine "bon" IPA| [bɔ̃] , feminine "bonne" IPA| [bɔn] "good"yntactically conditioned alternation
Syntactically conditioned alternations can be found in the
Insular Celtic languages , where words undergo various initialconsonant mutation s depending on their syntactic position. [cite journal |last=Green |first=Antony D. |year=2006 |title=The independence of phonology and morphology: The Celtic mutations |journal=Lingua |volume=116 |pages=1946–85 |issn=0024-3841 |url=http://roa.rutgers.edu/files/652-0404/652-GREEN-0-0.PDF |doi=10.1016/j.lingua.2004.09.002] For example, in Irish, an adjective undergoes lenition after a feminine singular noun:
*unmutated "mór" IPA| [mˠoːɾˠ] "big", mutated in "bean mhór" IPA| [bʲan woːɾˠ] "a big woman"In Welsh, anoun undergoes soft mutation when it is the direct object of afinite verb :
*unmutated "beic" IPA| [bəik] "bike", mutated in "Prynodd y ddynes feic" IPA| [ˈprənoð ə ˈðənɛs vəik] "The woman bought a bike"ee also
