+# Swedish (`sv`)
+
+Catalog: `src/i18n/locales/sv.json`. General rules: [TRANSLATORS.md](../TRANSLATORS.md).
+
+Translation source: [God's Eye View Sverige](https://github.com/Kajjan7610/Gods-view-sweden) by Kaj Obst, November 2026.
+
+## Style
+
+- Standard Swedish as in Swedish software and on Swedish authority sites (SMHI, Trafikverket, Polisen).
+- Actions and hints use the imperative without a pronoun: «Försök igen», «Klicka på en kamera för att aktivera den», «Välj en tagning först», «Tillåt mikrofonen och försök igen». Avoid «du»/«ni»; "your" becomes «egen» or is left out: «Egen RTL-SDR-mottagare», «Stationen ser din IP-adress» only where a person must be addressed.
+- Sentence case, not Title Case: "Live Flights" → «Liveflyg», "Provider Settings" → «Leverantörsinställningar». UPPERCASE English stays UPPERCASE: «LIVEDATA AV», NOT AN ALL-CLEAR → «INTE FARA ÖVER».
+- Compounds are written as one word, with a hyphen after a name, code or abbreviation: «datalager», «väderrutor», «TomTom-nyckel», «AIS-fartyg», «Street View-reserv». Never split a compound with a space.
+- Short labels, chips and HUD readouts stay short; use a standard abbreviation with a period over a wrapped line: RÄCKV., HAST., NEDERB., ÖVR., MEDD., FÖRST., KAL. «Jämför» is JFR, without a period.
+- The avionics codes HDG, BRG, CRS, DEST, SPD, ALT, GS, TRK, V/S, FOV and SQUAWK stay in English, as in the cockpit. Words in a sentence are translated: heading → «kurs», bearing → «bäring», range → «räckvidd».
+- A dash between clauses is a spaced en dash « – ». Quotes are ”…” (Swedish closing quotes on both sides).
+- Status and waiting messages: «Väntar på uppdatering», «Laddar …». Reasons after a dash stay lower case: «Scenen sparades inte – projektet är större än 5 MiB».
+- A layer named in a sentence takes its panel name in quotes: «Lagret ”Liveflyg” är inte aktiverat».
+- Rolling windows say their length: LAST YEAR → «SENASTE 12 MÅN.», LAST MONTH → «SENASTE 30 DAGARNA».
+- Keyboard keys: Mellanslag, Backsteg, Skift; Esc, Enter, Tab and letter keys stay.
+- Decimal comma in fixed text: «M4,4», «28,2710° N». Thousands separator is a space: «1 000 km». Formatted numbers come from `Intl` and are already Swedish.
+- Units: km, m, km/h, m/s, kn (knop), ft (fot), hPa, MW, h, min, s, d (dygn, in short readouts); in UPPERCASE text KM, KM/H, KN, FT, MIN, H, D. A space between number and unit, also before %: «{value} m», «{count} min», «50 %». `°` sticks to the number.
+- "ago": «för {count} min sedan», short «{count} min sedan». When a placeholder already holds a localized "ago" text (`{age}`, `{ago}`), do not add «sedan» again.
+- Compass points use O for öst and V for väst, as SMHI does: N, NNO, NO, ONO, O, OSO, SO, SSO, S, SSV, SV, VSV, V, VNV, NV, NNV; hemisphere letters N, S, O, V.
+- Routing: «Sväng {direction} in på {road}», «Fortsätt {direction}», «Ta {exit} avfarten» with ordinals «2:a», «3:e».
+
+## Plurals
+
+A `tn()` entry needs two forms. `Intl.PluralRules('sv')` picks:
+
+| Form    | Counts                      | Example     |
+| ------- | --------------------------- | ----------- |
+| `one`   | 1                           | 1 kamera    |
+| `other` | everything else: 0, 2, 1,5… | 3 kameror   |
+
+Abbreviated units and codes do not change: «{count} MEDD.».
