fast

Något som sitter stadigt och inte rör på sig.

fast (Swedish):

Meaning:
1. Solid / Firm / Fixed – Not moving or changing, physically stable.
2. Tight / Securely fixed – Something that is held firmly in place and does not easily come loose.
3. Quick / Rapid (Stylistic usage or in compounds, e.g., "köra fast" meaning "getting stuck," though "fast" means stuck here).
4. Fasting (rare in modern usage, mostly as noun fasta for fasting, abstaining from food).

Examples:

Produkten sitter fast på väggen. (The product is fixed on the wall.)
Skruven är fast. (The screw is tight.)
Bilen körde fast i snön. (The car got stuck in the snow.)

Differences to Similar Words:

Säkert / Starkt / Stabilt:
These can also mean secure or stable but in broader contexts—"fast" emphasizes physical tightness or being stuck rather than abstract safety ("säkert") or strength ("starkt").
Hårt:
Means hard (texture) rather than fixed. You can describe something as "hårt" (hard surface), while "fast" refers to it being unmovable or sturdy mounted.

Summary:

"fast" primarily describes something securely affixed, stable, or immovable in Swedish. It also appears in idiomatic expressions especially indicating something stuck or immobile.
