Syntheticism of verbal inflection
The syntheticism of verbal inflection in a given language is numerically represented referring to the maximum of inflectional categories that a single verb form can express simultaneously.1 Inflectional categories are grammatical features whose expression requires a distinct form of the verb.2
Types:
CpW=0: The language does not have verbal inflection.
CpW=X: The maximum of inflectional categories value is X.
1: In most languages, the maximum of inflectional categories per word value is a lower number than the total number of verbal inflectional categories. (See parameter Number of verbal inflectional categories.) This often occurs because certain features cannot be marked across the full paradigm, thus limiting their co-occurrence with other features.
2: The most common verbal inflectional categories are person and number; time, aspect, and mood (TAM); agreement, status (realis–irrealis), polarity (affirmative–negative), illocution (declarative, interrogative, imperative), and voice. Less frequently occurring inflectional categories include collective marking, inversion, honorifics, target quantification, focus, transitivity, reciprocity (as a feature of agreement), argument markers, object classifiers, non-specific referent marking, scope, deixis, movement, causatives (if relevant to the context). TAM should only be counted as a single unit if these features are not grammatically distinct in the given language.
