számú

számú is a Hungarian adjective formed from the noun szám, meaning number, with the suffix -ú. It denotes that something is designated by a number or belongs to a numbered set. The expression is typically used in combination with a numeral and a period, creating phrases such as 3. számú tanterem or 7. számú főút to identify a specific item within a sequence.

Common usage of számú appears in official designations, signage, and administrative documents. It is frequently seen in road or street names, building or room identifiers, and in lists of annexes or appendices. Examples include 3. számú főút (Main Road No. 3), 1. számú melléklet (Annex No. 1), or 4. számú tanterem (Classroom No. 4). The construction helps readers quickly locate a particular unit or element in a larger collection.

Grammatically, számú is an adjective that precedes the noun it modifies. The numeral part is usually written with a period after the number, as in "X. számú." The same lemma can be used with various nouns to indicate different numbered items, and it is common across formal and semi-formal Hungarian contexts.

In summary, számú functions as a concise marker for numbered designations and is widely used in public and administrative language to pinpoint specific items within organized sets.
