flyga means "to fly" — what a bird does in the air and what you do when you travel by plane. It is a strong verb of the y–ö–u type, with principal parts flyga – flög – flugit. The infinitive and present carry y, the past rounds to ö in flög, and the supine shifts to u in flugit — a vowel change that catches almost every learner, who expects flygit. Knowing which mode of transport takes flyga and which takes åka is the other half of using this verb naturally.
Principal parts
| Infinitive | Present | Preteritum (past) | Supine | Imperative | Group |
|---|---|---|---|---|---|
| flyga | flyger | flög | flugit | flyg | Group 4 (strong), y–ö–u |
Track the vowel carefully — this verb changes it three ways. Infinitive and present y (flyga, flyger), past ö (flög), supine u (flugit). The agreeing past participle is flugen / fluget / flugna, also with u. The trap to drill: the supine is flugit, never flygit; the y survives only in the infinitive and present.
Planet flyger direkt till Köpenhamn.
The plane flies direct to Copenhagen. flyger — present.
Vi flög till Spanien förra sommaren.
We flew to Spain last summer. flög — past, vowel ö.
Har du någonsin flugit business class?
Have you ever flown business class? har flugit — perfect, supine vowel u.
Use 1: present, past and perfect
The three tenses follow the principal parts. Present flyger covers "fly" and "am flying." The past flög is the bare vowel-changed stem with ö. The perfect is har flugit; the pluperfect is hade flugit. Watch the jump from ö in the past to u in the supine — they are not the same vowel.
Måsarna flyger lågt över hamnen i dag.
The gulls are flying low over the harbour today. Present flyger.
Piloten flög oss genom oväder utan problem.
The pilot flew us through the storm without trouble. flög — simple past with ö.
Tranorna hade redan flugit söderut när vi kom.
The cranes had already flown south by the time we arrived. hade flugit — pluperfect, supine flugit.
Use 2: flying through the air
In its literal sense flyga describes anything moving through the air under its own power or thrown — birds, insects, planes, and figuratively things that move fast or get flung. The same y–ö–u pattern holds throughout.
En geting flög in genom det öppna fönstret.
A wasp flew in through the open window. flög — past, literal flight.
Tiden flyger när man har roligt.
Time flies when you're having fun. flyger — figurative, present.
Bollen kom flygande rakt mot mig.
The ball came flying straight at me. flygande — present participle.
Use 3: flyga vs åka — air travel only
This is the usage point worth memorising. flyga is for travelling by air; for travel on the ground you use åka (åka tåg, åka bil, åka buss). You can say flyga till Berlin or, equivalently, åka flyg till Berlin ("go by plane"), but you never flyga to a place you reach by road or rail. The mismatch with English is real: English "fly" sometimes drifts to mean "move fast" (a car that flew down the motorway), but Swedish keeps flyga tied to the air — for speed on the ground you'd reach for susa or rusa instead. So treat flyga as a literal verb of air travel, and let the choice between flyga and åka signal your mode of transport automatically.
Vi flyger till Berlin och åker tåg hem.
We're flying to Berlin and taking the train home. flyga for air, åka for the ground leg.
Det är billigare att åka buss än att flyga.
It's cheaper to take the bus than to fly. Contrast åka (ground) and flyga (air).
Jag flyger iväg på torsdag och är borta en vecka.
I'm flying off on Thursday and away for a week. flyga iväg — fly off.
Common Mistakes
❌ Vi flygade till Rom.
Incorrect — flyga is strong and takes no -ade ending. The past is the vowel-changed flög.
✅ Vi flög till Rom.
We flew to Rome.
❌ Har du flygit förut? (y in the supine)
Incorrect — the supine is flugit with u, not flygit. The y survives only in flyga/flyger.
✅ Har du flugit förut?
Have you flown before?
❌ Vi flög med tåg till Göteborg.
Incorrect — you can't 'fly' by train. Ground transport takes åka: åka tåg.
✅ Vi åkte tåg till Göteborg.
We took the train to Gothenburg.
❌ Hon har flög hem. (past for supine)
Incorrect — after har you need the supine flugit, not the past flög.
✅ Hon har flugit hem.
She has flown home.

- Index of Strong Verbs by PatternB1 — A navigable index of the common Swedish strong verbs, grouped by ablaut pattern rather than alphabetically — i–e–i (skriva/skrev/skrivit), i–a–u (dricka/drack/druckit), a–o–a (ta/tog/tagit), and the irregular/contracted set (gå/gick/gått). Each group is a four-part table of principal parts with English cognate hints, because organising strong verbs by shared vowel pattern turns a scary list into a few learnable families.
- Strong Verbs: Overview and Principal PartsB1 — Strong verbs (Group 4) don't add a past-tense ending — they change their stem vowel across three principal parts: skriva–skrev–skrivit. The vowel moves in recurring patterns (ablaut) that Swedish shares with English: i–a–u is the same machinery as sing–sang–sung. This page teaches you to read principal parts, recognise the classes, and leverage the English cognate vowels so memorisation becomes pattern-recognition.
- Supine vs Past ParticipleB1 — The single Swedish verb-form distinction English has no equivalent for: the supine (har skrivit — fixed, invariable, only after ha) versus the past participle (en skriven bok, ett skrivet brev, skrivna böcker — fully agreeing, used as adjective and in the passive). English collapses both into one '-en' word; Swedish splits them, and confusing the two (*har skriven, *en skrivit bok) is a hallmark learner error.
