In linguistics, syncretism exists when functionally distinct occurrences of a single lexeme, morph or phone are identical in form. The term arose in historical linguistics, referring to the convergence of morphological forms within inflectional paradigms. In such cases, a former distinction has been 'syncretized'.[1] The term syncretism is often used when a fairly regular pattern can be observed across a paradigm.[2]

Syncretism can arise through either phonological or morphological change. In the case of phonological change, originally distinct forms change to be pronounced identically, so that their distinctness is lost. Such change can often be observed in the modern German verb paradigm: the infinitive nehmen 'to take' comes from Old High German neman, the first person plural declension nehmen comes from nemēm, and the third person plural nehmen comes from nemant. This is also an example of syncretism manifested in lexemes.

Phonological change in the German verb paradigm
Old High German --> Modern German
infinitive neman nehmen
1.PL nemēm nehmen
3.PL. nemant nehmen

In the case of morphological change, one form stops being used and is replaced by the other. This change can be exemplified by the syncretism in Latin's third-declension nouns, whose nouns take the same form in nominative and vocative cases.



In English, syncretism led to the loss of case marking and the stabilization of word order.[3] For example, the nominative and accusative forms of you are the same, whereas he/him, she/her, etc., have different forms depending on grammatical case.

Another English example for syncretism can be observed in most English verb paradigms: there is no morphological distinction between the past participle and the passive participle, and, often, the past tense.

Syncretism in English verb paradigms
past tense past participle passive participle
to walk walked walked walked
to win won won won

The syncretism observed here differs from the lexical syncretism observed in English personal pronouns inasmuch that the syncretism manifests itself in the suffix or stem change in the case of walked and won, respectively.


In Latin, the nominative and vocative of third-declension nouns have the same form (e.g. rēx 'king' is both nominative and vocative singular), distributing syncretism in case marking. Another observation is the distinction between dative and ablative, which is present in singular (e.g., puellae 'girl-DAT.SG' and puella 'girl-ABL.SG'), but not anymore in plural (e.g., puellis 'girl-DAT.PL/girl-ABL.PL'.[2]


Similarly, in German, the infinitive, first person plural present, and third person plural present of almost all verbs are identical in form (e.g. nehmen "to take", wir nehmen "we take", sie nehmen "they take").

Other languagesEdit

In the Finnic languages, such as Finnish and Estonian, there is syncretism between the accusative and genitive singular case forms, and the nominative and accusative plural case forms.

Accounts for syncretismEdit

There exists a cross-linguistic typological investigation of syncretism ("The Syntax-Morphology Interface: A Study of Syncretism" by Baermann, Brown and Corbett, 2005)[4]. This study explores the logical space of syncretism, i.e., what features may be involved, and what sort of patterns do these describe. On the other hand, it provided a diverse sampling of the world’s languages.

Other studies on syncretism include "A Distributed Morphology Approach to Syncretism in Russian Noun inflection" (Müller 2004)[5] in which Müller provides a systematic account for Russian noun inflection.
