number. Verbs are traditionally divided into four classes: transitive verbs, intransitive verbs, verbs with no transitive counterparts (medial verbs) and indirect verbs. There are numerous irregular verbs in Georgian, but they all belong to one of these classes. Each class uses different strategies to build the verb complex, with irregular verbs employing somewhat different formations. Verb classes Transitive verbs (Class 1 verbs) Class 1 verbs generally have a subject and a direct object. Some examples are "eat", "kill" and "receive". This class also includes causatives (the equivalent of "make someone do something") and the causative verbal form of adjectives (for example, "make someone deaf"). There are a few verbs in Class 3 that behave like transitive verbs of Class 1 in terms of their conjugations, such as sneeze and cough (see below). Intransitive verbs (Class 2 verbs) Intransitive verbs only have a subject and no direct object (though a few govern an indirect object marked simply with the dative case). Most verbs in this class have a subject that does not perform or control the action of the verb (for example, "die", "happen"). The passive voice of Class 1 transitive verbs belong in this class too, for example "be eaten", "be killed" and "be received". In addition, the verbal form of adjectives also have their intransitive counterparts: the intransitive verb for the adjective "deaf" is "to become deaf". Medial verbs (Class 3 verbs) Verbs in Class 3 are usually intransitive verbs, but unlike Class 2 verbs, they mark their subject using the ergative case. Most verbs of motion (such as "swim" and "roll") and verbs about weather (such as "rain" and "snow") belong to this class. Although these verbs are described as not having transitive counterparts (such as "cry"), some of them still have direct objects, such as "learn" and "study". Verbs that are derived from loan words also belong to this class. The intransitive verbs in Classes 2 and 3, when taken together, seem to be conjugated differently based on a form of active alignment (see the section on morphosyntactic alignment). Indirect verbs (Class 4 verbs) Verbs that convey the meaning of emotion and prolonged state belong to this class. The verbs "want" and "can" also belong to this class. Other common examples of Class 4 verbs are "sleep", "miss", "envy" and "believe". These verbs typically mark the subject with the dative and the object with the nominative. Stative
