An inclusive/exclusive distinction may occur among personal pronouns, possessive pronouns, possessive affixes, or verbal inflection. Languages with this distinction differentiate a non-plural first person (‘we’) that includes the listener from one that excludes the listener. Verbal inflection involves person-marking grammatical morphemes (optional or required) that can only attach to the main or auxiliary verb.
NoCjg: Verbal inflection does not exist.
Pl1=Sg1: First-person singular and non-singular forms are identical; number is determined by contextual cues.
Pl1=Pl1: First-person plural does not have an inclusive/exclusive distinction.
Pl1Excl: Only the exclusive first-person plural form is distinguished; first-person singular and plural are otherwise identical.
Pl1Icl: Only the inclusive first-person plural form is distinguished; first-person singular and plural are otherwise identical.
Pl1InclNotExcl: Distinct forms exist for first-person singular, exclusive first-person plural, and inclusive first-person plural.
Note: If the verbal inflection system includes non-binary grammatical numbers, such as dual, trial, or paucal, this should be noted in the commentary, particularly if these numbers differ from the plural in their distinction of inclusivity.
 To constitute verbal inflection, these morphemes (including zero morphemes) must attach to the verb. Other syntactic positions, such as the first morpheme in the sentence, are not equivalent.
 While this type is theoretically possible, no examples of it are known to exist.
 Synthetic marking does not constitute a morphological strategy and should therefore not be considered for this value. Specifically, the first-person singular and exclusive first-person plural may differ only in their plural marker; if this marker is shared by the inclusive first-person plural, the language should be classified as Pl1InclNotExcl.
