staðföstum

staðföstum is a grammatical form in Icelandic. It is the dative plural form of the adjective staðföstur, meaning stationary or fixed in place. The form is used when describing a plural noun in the dative case, such as after prepositions that govern the dative or within a dative noun phrase. The general sense is that something is not moving and is anchored or installed in a particular location.

Etymology and meaning: The adjective is built from staður, meaning place, and fastur, meaning fixed. The compound sense conveys that something is fixed in position rather than mobile.

Usage: staðföstum commonly appears in technical, legal, or scientific writing where fixed installations or equipment are described. It describes objects that are intended to remain in place rather than movable. For example, phrases like staðföstum tækjum or staðföstum vélum convey “stationary equipment” or “stationary machines” in the dative plural. Such usage helps specify installation status or mounting conditions in manuals, specifications, and regulations.

Grammar note: Icelandic adjectives decline to reflect the gender, number, and case of the nouns they modify. staðföstum represents the dative plural form used with plural nouns in the dative case.
