családfából

Családfából is a Hungarian adverbial phrase meaning “from the family tree.” It is used to indicate that information, data, or traits originate in or are derived from genealogical records or a family history. The expression can appear in both scholarly writing and more general prose to signal the provenance of facts or conclusions.

Etymology and grammar: The phrase is formed from the noun családfa (family tree) combined with the ablative suffix -ból/- ből, which marks origin or source. In sentences it functions as a frame for the source of information and is typically followed by verbs or verbal phrases such as kiderül (it becomes clear), származik (derives from), or igazolja (confirms), among others.

Usage and examples: Családfából kiderül, hogy a felmenői között volt író. A kutatás a családfából származó adatok alapján készült. A történet a családfából vett részletek alapján rekonstruálható. These examples illustrate how the phrase links conclusions or narratives to genealogical sources rather than to other kinds of records.

Context and related terms: Családfa (family tree) and családkutatás (genealogy) are closely related concepts. The expression is most common in discussions of ancestry, hereditary traits, or historical narratives where the basis is a documented family lineage. While not a technical term in genetics, it remains a useful linguistic tool in genealogical, historical, and biographical writing to indicate source provenance.
