Nyílásán

Nyílásán is a Hungarian grammatical form, not a standalone concept. It derives from the noun nyílás, which means opening, aperture, or gap. The noun nyílás is formed from the verb nyílni (to open) with the nominalizing suffix -ás. Nyílásán represents a locative inflection of nyílás, indicating position at or on the opening of something.

In use, nyílásán appears in phrases that describe location or movement through an opening. It is commonly paired with postpositions such as keresztül (through) or át (across) to express movement through the opening. For example: A fény a nyílásán keresztül bevilágította a termet. (The light illuminated the room through the opening.) A patkány a nyílásán át menekült. (The rat escaped through the opening.)

Common contexts include architectural features (doors, windows, vents), natural formations (caves, cracks), and mechanical or biological passages where something passes via an opening. The form highlights the opening itself as a point of reference for location or passage rather than describing the entire object.

Phonology and spelling of nyílásán follow standard Hungarian rules: the word is pronounced roughly as nyí-lá-sán, with stress typically on the first syllable. The accent and suffixes align with Hungarian suffixation patterns and do not alter the base meaning of nyílás beyond indicating location at its opening.
