{{Short description|Linguistic concept}}
In language change, '''analogical change''' occurs when one linguistic sign is changed in either form or meaning to reflect another item in the language system on the basis of analogy or perceived similarity. In contrast to regular sound change, analogy is driven by idiosyncratic cognitive factors and applies irregularly across a language system. This leads to what is known as Sturtevant's paradox: sound change is regular, but produces irregularity; analogy is irregular, but produces regularity.<ref name=":0">{{Cite book |last=Millar |first=Robert McColl |title=Trask's Historical Linguistics |publisher=Routledge |year=2015 |isbn=978-0-415-70657-5 |location=London |pages=99–101}}</ref>

== Analogy in child language acquisition == Analogy plays an important role in child language acquisition. The relationship between language acquisition and language change is well established,<ref>{{Cite journal |last=Louden |first=M. L. |year=2003 |title=Review Article: Child Language Acquisition and Language Change |journal=Diachronica |volume=20 |issue=1 |pages=167–183|doi=10.1075/dia.20.1.09lou }}</ref> and while both adult speakers and children can be innovators of morphophonetic and morphosyntactic change,<ref>{{Cite book |last=Meisel |first=Jürgen M. |title=First and second language acquisition: Parallels and differences |publisher=Cambridge University Press |year=2011 |location=Cambridge |page=124 |doi=10.1017/CBO9780511862694|isbn=978-0-521-55294-3 }}</ref> analogy used in child language acquisition likely forms one major source of analogical change.
During the acquisition of grammatical change, children are prone to overregularization, in which the children extends a particular grammatical rule to apply to irregular forms by analogy, such as created forms such as ''mans'' and ''mouses'' for the plural of ''man'' and ''mouse'' on the basis of the regular English plural. If this overregularization becomes established in the child's grammar and is adopted by many speakers, it would lead to analogical change in the form of leveling.<ref>{{Cite book |last=Barber |first=C. |title=The English language: A Historical Introduction |year=2009 |edition=2nd |page=47}}</ref>
== Types of analogical change == Analogical change does not represent a single process, but rather a family of different language change processes which all follow the general principle of irregularly changing one form to 'match' another form or a pattern observed among several other forms.
=== Proportional analogy === '''Proportional analogy''' or '''four-part analogy''' is the simplest form of analogical change, representing the change or introduction of a form on the basis of analogy with a pattern that can be expressed by a single form. This type of analogical change is often diagrammatized with a proportion, in which rows represent paradigms while columns represent dimensions of similarity.<ref name=":0" /> Thus, for example, the analogy which generated ''flammable'' from ''inflammable'' on the basis of the pattern of ''in-'' prefixes could summarised as a proportional analogy with the following proportion:<blockquote><math>\begin{matrix} inarticulate & : & articulate \\ inflammable & : & ? \end{matrix}</math></blockquote>where the <?> represents the new, albeit overregularized form, ''flammable'', with both ''inflammable'' and ''flammable'' having the same meaning.
=== Creation, maintenance and restoration === '''Analogical creation''' refers to cases when analogy creates a new word or form of a word.<ref name=":0" /> The example of ''flammable,'' having the same meaning as ''inflammable,'' is an example of analogical creation, as the word ''flammable'' has been created and added to the language system.
'''Analogical maintenance''' occurs when a regular sound change is prevented from occurring on the basis of analogy. In completed changes, this is indiscernible from '''analogical restoration''', in which a regular sound change is reversed on the basis of analogy.<ref name=":0" /> An example of analogical maintenance would be the perseverance of /w/ in ''swollen'' by analogy with the present tense ''swell'' (contrast with ''sword'', where the /w/ is lost by regular sound change).
=== Leveling === '''Leveling''' involves the elimination of alternations within a paradigm.<ref name=":1">{{Cite book |last=Hock |first=Hans Henrich |title=The Handbook of Historical Linguistics |publisher=Blackwell |year=2003 |editor-last=Joseph |editor-first=Brian D. |location=Oxford |pages=441–460 |chapter=Analogical Change |editor-last2=Janda |editor-first2=Richard D.}}</ref> This typically occurs when a particular variation no longer signals an important morphological distinction. For example, Old English (OE) distinguished past singular and past plural forms of the verb {{lang|ang|ceosan}}, {{lang|ang|ceas}} and {{lang|ang|curon}} respectively, but these were leveled to give a single Modern English (LME) past, ''chose''.
=== Contamination === '''Contamination''' refers to analogical change wherein a particular form influences the pronunciation of a semantically related form, without bringing about any change in the meaning of that form.<ref name=":1" /> An example of contamination may be seen in the change from Middle English (ME) {{lang|enm|male/femelle}} > LME ''male/female''.<ref name=":0" />
=== Recomposition, folk etymology, and hypercorrection === '''Recomposition''' and '''folk etymology''' are related processes that assign transparent compound structure to previously simple words.<ref name=":1" /> The two kinds of change are differentiated by the fact that the former accurately reconstructs some previous form of complex structure of the word, while the latter imposes an analysis of the word which was never accurate. An example of recomposition is the change from OE {{lang|ang|hūs-wīf}} {{gloss|house-wife}} > ''hussif'' (> 'hussy') > LME ''house-wife.''
'''Hypercorrections''' may also become established in a language, leading to a further kind of analogical change. An example of a change resulting from hypercorrection would be the change of ME {{lang|enm|autor}} > LME ''author'' on the basis of perceived similarity to ME {{lang|enm|trone}} > LME ''throne'', the latter in turn being an analogical change on the basis of the Greek {{Transliteration|grc|thronos}}.<ref name=":0" />
== Examples of analogical change ==
=== Phonology === Leveling analogical change can occur in sound change when some forms in a given paradigm provide a correct environment for a change, and with forms which do not provide the correct environment for the sound change being modified to exemplify the same changes. This kind of change may be exemplified from vowel changes in Old English, where forms such as ''whale'' (from OE {{lang|ang|hwæl}}) take a long vowel rather than the short vowel expected by regular sound change due to the vowel being lengthened in other forms in the same paradigm (in this case, the plural ''whales'', cf. ''staff/staves'').<ref>{{Cite book |last=Dresher |first=B. Elan |title=Analogy, Levelling, Markedness : Principles of Change in Phonology and Morphology |publisher=De Gruyter Mouton |year=2000 |editor-last=Lahiri |editor-first=Aditi |page=50 |chapter=Analogical leveling of vowel length in West Germanic |doi=10.1515/9783110808933.47|isbn=978-3-11-016750-4 }}</ref>
=== Morphology === Analogical change in morphology involves changing the items in one inflectional paradigm to fit with the pattern observed in another on the basis of phonological similarities. This may be exemplified in English by the plural of ''octopus''. This is a Greek borrowed word, and so should take a plural form ''octopodes''. However, English has many nouns of Latin origin with singular forms ending -''us'' and plural forms ending ''-i'', such as ''cactus/cacti, radius/radii'', etc. Thus, an analogical proportion can be established:
<math display="block">\begin{matrix} cactus & : & cacti \\ octopus & : & ? \end{matrix}</math>
On the basis of this analogy, the plural ''octopi'' is established.<ref name=":0" /> (Some varieties may have ''octopuses'' instead, which is instead derived from the productive plural rule of English morphology.)
