blåses

Blåses is a grammatical form used in Swedish and Norwegian to express that air, gas or other substances are being blown by an external force. It is the present passive (presens passiv) of the verb blåsa in Swedish and av å blåse in Norwegian Bokmål. In both languages the form is used when the agent behind the action is unknown, general, or indicated by a preposition such as av.

As a present passive, blåses shifts the focus from the agent to the thing affected by the action. This makes it suitable for describing processes where the doer is not specified or not important. In practical use, blåses often appears in contexts such as ventilation, meteorology, and engineering. For example: "Luft blåses in i rummet genom ventilationskanalen" in Swedish, and "Luft blåses inn i rommet av ventilasjonen" in Norwegian.

Etymology traces blåsa to the Old Norse blása, with cognates in other Germanic languages. The form blåses follows the general pattern of Swedish and Norwegian verbs that create the present passive by adding the suffix -s to the verb stem. The construction is common in both formal and everyday language, and it can be found in technical descriptions as well as weather-related statements, where the action is a general, observable process rather than a specific agent-driven event.

In summary, blåses denotes something being blown in the present passive voice in Swedish and Norwegian, and is used across contexts to describe the movement of air, gas, or similar substances by an external force.
