Other than /maj/, there are no special plural forms of the pronouns, as they are inflected for number along with other nouns. Number Inflection in Nouns While English distinguishes between singular and plural, Maidu distinguishes singular, dual, and plural. These inflections are most often used in conjunction with the pronouns, and are much less commonly used with other nouns. Both dual /c'o/ and plural /cy/ suffixes have several allomorphs. Along with these, there is a second plural morpheme /t'yt'y/ which indicates both plurality and a diminutive sense. Maidu verbs consist of the verbal theme along a series of suffixes. Similar to nouns, the verb stems in Maidu result from several different sources. Some verbs, like /sol/ 'sing' are composed of a single simple root. Other verbs include a noun in the verb stem, such as /k'awba/ 'to dig a hole', which is a compound of /k'aw/ 'dirt' and /ba/ 'to dig.' Still other compound verb stems result from the conjunction of two separate verb roots, as in /t'ikc'e/ 'to believe', from /t'ik/ 'to have enough' and /c'e/ 'to see.' Like nouns, some verb stems include a component that has no meaning on its own, such as /bokweje/ 'to invoke', where /weje/ means 'to talk' and /bok/ has no known meaning. Still others are the result of a verb and an auxiliary verb, and finally a set of verbs involving motion uses /'y/ as its first compound. Verb Theme The verb theme is a combination of the verb stem along with one or more thematic suffixes. All thematic suffixes are optional, and thus may be excluded from the verb, with the base stem acting as the theme on its own. •Causative •Designation of verbal object •Motion-Location •Negative •Aspectual •Evidential  Causative The causative suffix /ti/ indicates that the actor is causing an action to occur, as in "ma dondom 'as te 'ynotik'as", which means 'I walked the child, holding his hand' or 'I caused the child to walk, holding (his) hand.' This morpheme also occurs in words like /wonoti/ 'to kill', literally 'to cause to die.'
