exclamation interjection expresses strong emotion by the speaker.
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.
Some common exclamation interjections in Koiné Greek include the terms αμην, ουαι, ωσαννα, χαιρη (perhaps others?). examples of common interjections in the New Testament (for example, “Woe!” or “Amen” or “Hosanna”)
