«هَيَّا هَيَّا وَهَلُمَّ تَهَيَّأْ»
Hurry, come along, and get ready.
Hayyā urges action; halumma summons someone to come or attend; tahayyaʾ means “get prepared.” The final verb is an imperative from the form V verb tahayyaʾa, root h-y-ʾ.
These are not simply three interchangeable words. The sequence conveys a servant being mobilised to prepare the guest’s reception promptly.
