Pólusai

Pólusai is the Hungarian plural possessive form of the noun pólus, meaning “poles.” It is used to indicate possession by a third person (singular or plural) and functions as a possessive plural ending attached to the stem pólus. The plain plural form is pólusok, which is used when possession is not specified; pólusai specifies whose poles are being referred to.

In use, pólusai appears in scientific and descriptive contexts where something has multiple poles. The form combines the root pólus with the suffix -ai, following Hungarian vowel harmony rules. The word remains a form of the noun rather than a separate lexical item.

Typical contexts include geography, physics, magnetism, and biology, where one speaks of the poles belonging to an object or system, such as a planet, magnet, or cell. For example, one might say “a Föld pólusai” to mean “the Earth’s poles,” or “az atom magnetos pólusai” to refer to an atom’s magnetic poles, with the possessive plural marker indicating ownership by the preceding noun.

Pólusai should be distinguished from the bare plural pólusok, which simply denotes multiple poles without specifying ownership. The form póliusai is thus primarily a grammatical tool for expressing possessive relations in Hungarian, rather than a separate lexical entry. See also pólus, pólusok, északi pólus, déli pólus.
