The present article focuses on the functions of the second-person forms of the imperative and the optative mood that occur in independent clauses in the Gothic Gospels. Both mood forms carry the incentive (injunctive) meaning and thus have been viewed as interchangeable. This article illustrates, however, that the imperative and the optative are opposed in terms of their grammatical meaning. Specifically, while the imperative mood expresses a high degree of performativity and control over a caused action that is to be performed by a specific addressee, the optative generally denotes the causation of an uncontrolled or a less-controlled action, often by an indefinite or a generalized addressee, which may be presented as a wish of the speaker, and thus may exhibit a low degree of performativity. This grammatical opposition is formed as a means of rendering the senses of the original Greek text of the gospels in the Gothic language, and it plays an essential text-building role in Gothic. Speech acts of varying degrees of performativity (“order” and “request,” vs “advice” and “instruction,” i.e. “eternal moral commandments”) are strongly associated with two registers within the text of the gospels: (1) descriptions of events in the life of Jesus Christ: His actions (the calling of the apostles, the healings, etc.) and the appeals to Him with requests for help; and (2) the preaching of Jesus Christ: His calls and appeals to His audience with the intent of teaching them. Moreover, the two grammatical forms of the incentive (injunctive), the imperative and the optative, act as the means of the stylistic coloring of these two registers: the descriptive prose and the parenetic contexts (“expressively saturated direct speech”). The article further argues for a direct connection between the lexical meaning of the verb and its ability to form the second-person imperative and optative: the imperative is generally formed by voluntary perfective verbs, while the optative is formed by aspect-neutral involuntary verbs used in atelic meanings.
