יוֹאָח

Based on the given data, the word "yo.ach" (Strong's number H3098K) appears to be a proper noun, specifically a given name, in the Hebrew language. It is defined as "Joah," which is the transliteration of the word from the original Hebrew script. This name occurs only once in the Bible, indicating that it may be a unique or relatively rare name in the context of the text. The significance of this word lies in its individuality as a specific personal name. As a proper noun, it does not carry a broader semantic meaning but rather serves as a unique identifier for one individual within the biblical narrative. The fact that it occurs only once suggests that the author of the text chose this name intentionally, possibly to convey a particular detail about the character or to emphasize their distinct role within the story. Further analysis of the surrounding context would be needed to better understand the role of Joah in the narrative.
