μονογενής
monogenḗs
G3439 substantive adjective
SILEX Entry
Definition
Single or unique of its kind, only one in a category or relationship; in familial contexts, refers to an only child, especially an only son or daughter. Also denotes singularity or uniqueness more broadly—something or someone without parallel or equal, often in reference to an entity's distinctive nature, status, or relationship, especially in expressions emphasizing exceptional or unique character (e.g., 'one and only').
Semantic Range
only child, only son/daughter, unique individual, only one of its kind, unique in category, singular, sole
Root / Etymology
From μόνος ('alone, only, single') and γεννάω (contracted here as -γενής, from γίνομαι, 'to become, to be generated'); thus, 'only-generated' or 'only one of a kind.' Root: μόν- + -γενής.
Historical & Contextual Notes
In classical and Hellenistic Greek, μονογενής primarily described an only child (especially an only son), but could also refer to a unique or unmatched entity. In the Septuagint, it frequently translates Hebrew yāḥîd, which means an only or beloved child. In the New Testament, the term can refer to both biological 'only child' and—in theological contexts—a unique or singular relationship (not necessarily entailing physical birth or generation). Traditional English translations often render μονογενής as 'only begotten,' but most modern scholarship recognizes that the emphasis is on uniqueness rather than the act of begetting or generation. It does not intrinsically imply a derivational relationship, but rather the quality of being unique, one of a kind, or sole in its category. Not limited to familial relationships, the word is also used of unique animals, objects, or roles. Distinct from πρωτοτόκος, which means 'firstborn.' In some philosophical and theological texts, μονογενής acquires a specialized, technical sense of 'uniquely generated' or 'one and only.'
Original Strong's Gloss (1890)
from μόνος and γίνομαι; only-born, i.e. sole:--only (begotten, child).
