directive interjection is an interjection that expresses a direct command.
Interjections usually appear at the beginning of a sentence or clause and are grammatically disconnected from the rest of the sentence. As in many languages, interjections are often “natural sounds”, that is, vocal gestures or sounds that a person utters when experiencing certain emotions. Interjections can be used to express both positive and negative emotions.
A directive interjection expresses a command such as “look!” (reference) or “come!” (John 1:29). Some common directive interjections in Koiné Greek include the terms ιδου, δευτε, δευρο (perhaps others?).
