Elsfokú

Elsőfokú, commonly written elsfokú in non-diacritic texts, is a Hungarian adjective meaning "of the first degree" or "primary." It is formed from első (first) and fok (degree, level). The term is used across domains to indicate something that is at the initial, base, or simplest level within a given classification, and the exact sense depends on context.

Mathematics: In mathematical language, elsfokú is applied to objects of degree one. A first-degree polynomial, such as p(x) = a x + b with a ≠ 0, is linear. A first-degree equation in one variable likewise is linear.

Law and administration: In legal and public administration contexts, elsőfokú denotes decisions, judgments, or proceedings that occur at the first instance, i.e., before appeals to higher courts or authorities. The counterpart concepts include másodfokú (second instance) or fellebbezés.

Other uses: The adjective also appears in education and governance to indicate primary or initial levels where the term is common in official language.
