(By Ljuba N. Veselinova): "This chapter shows the distribution of suppletion according to verbal number. The term verbal number requires some clarification: number as a verbal category can reflect the number of times an action is done or the number of participants in the action. When we say that a verb or verb phrase in an Indo-European language, say French, is in the plural, as in ils étaient fatigués ('they were tired'), what we mean is that the verb phrase étaient fatigués agrees with the subject ils in number. The term plural verbs (or pluractional verbs) in many of the languages to be discussed below, on the other hand, refers to any or all of the following senses: the action is performed several times (iterative), or at several places (distributive), or the action affects or involves several participants."
