The word "υἱός" (huios) primarily means "son" in the usual sense, referring to a male child or descendant. It can also be used more broadly to indicate lineage, posterity, or connection to a group, quality, or characteristic (e.g., "sons of light" or "sons of disobedience"). Additionally, it is used metaphorically in various contexts, including as a title for Jesus, emphasizing his unique relationship to God or his humanity and representative role.
