Focului

Focului is a Romanian word-form that appears as the genitive and dative singular of the masculine noun foc (fire). In Romanian, nouns often take a definite article as a suffix; the definite singular nominative is focul (the fire), and the genitive/dative singular is focului (of the fire, to the fire). The form focului is therefore used to express possession or to mark the indirect object in phrases where the noun is definite.

Etymology and morphology: The noun foc derives from Latin focus, meaning hearth. Over time, Romanian retained the basic meaning of fire and developed the definite article as a suffix, yielding forms such as focul and focului. The plural forms are focuri (fires) and focurilor (of the fires), with focului serving the singular genitive/dative role.

Usage: Focului functions similarly to other genitive/dative singular forms and appears in contexts such as possession or description of a property related to fire. Typical phrases include the light and heat associated with a fire: Lumina focului (the light of the fire) and Căldura focului (the heat of the fire).

Examples:

- Lumina focului a luminat camera.

- Căldura focului se simțea în toată casa.
