fást

Fäst is the past participle form of the Swedish verb fästa, which means to attach or fasten. In modern Swedish it is used to describe something that has been fixed or secured, often in combination with auxiliary verbs such as har or är. For example, “Skruven är fäst i väggen” means the screw is fastened to the wall. The simple past tense of fästa is fäste, as in “han fäste plåten” (he fastened the plate).

In addition to its participial use, fästa forms the basis of related words and phrases. The noun fäste, meaning an attachment, mounting, or fixing point, is common in mechanical and construction contexts. Plural forms include fästen, referring to multiple attachments or mounts. The concept of fäste covers both the act of securing something and the resulting secure connection.

Etymology and related languages: fästa is an older Swedish verb with cognates in other Germanic languages. It is related to forms in Danish and Norwegian that convey the idea of fastening or fixing. The development of the word parallels the general Germanic roots for “fasten” or “fix.”

Usage notes: fäst typically appears in passive or perfect constructions (är fäst, har fäst) to indicate completed fastening. It can also function adjectivally to describe a component that has already been secured. In contrast, unfastening is expressed with verbs like lossa or losat.
