What is the meaning of the name Achiyahu ?

The baby name Achiyahu is a Male name , 4 syllables long and is pronounced ah-khee-YAH-hoo.

Achiyahu is Hebrew in Origin.

From the Hebrew אֲחִיָּהוּ (Achiyahu), the name joins achi (“my brother”) with the theophoric -yahu, a form of the divine name YHWH. It is commonly interpreted as “Yahweh is my brother” or “brother of Yah(weh),” expressing kin-like closeness, loyalty, and divine protection. The shorter form אֲחִיָּה (Achiya/Achiyah) appears alongside the longer -yahu ending, a pattern typical in Judah where many names bore the YHWH element.

Achiyahu is attested across the Hebrew Bible, borne by figures such as Ahijah the Shilonite, the prophet who addressed Jeroboam (1 Kings), and by priests and officials in Samuel–Kings–Chronicles. The name’s spellings vary by period and source, reflecting scribal alternation between -yahu and -yah. Modern variants include Achiya, Ahiya, and Achiyah; Anglicized forms are Ahijah, with Latin Ahias and Greek Achias. Predominantly masculine, it also sees limited unisex use in modern Hebrew contexts.
