bo ("to live, to reside, to dwell") is one of the first verbs you will ever need in Norwegian, because the first thing anyone asks a newcomer is Hvor bor du? — "Where do you live?" It is short, extremely common, and grammatically it is the textbook example of a weak Class 4 verb: a verb whose stem ends in a stressed vowel, which forces a doubled consonant in the past (-dde / -dd). It also sits at the heart of a distinction that trips up every English speaker: Norwegian splits English "live" into bo (reside somewhere) and leve (be alive, live a life).

Why the consonant doubles: weak Class 4
Class 4 contains the short verbs whose infinitive ends in a long, stressed vowel: bo, tro, bli, gro, snu, ro. Because there is no consonant in the stem to attach a normal -de/-te ending to, Norwegian inserts and doubles a d: the doubled consonant is the spelling's way of signalling that the preceding vowel is short in the past form. So the system is:
- Infinitive: bo (long o)
- Preterite: bodde (vowel shortens, d doubles, add -e)
- Supine: bodd (same doubled d, no -e)
This is the same machinery you will see in tro → trodde → trodd ("believe") and bli → ble → blitt (irregular, but same family feel). The doubling is not decorative — it is the only thing distinguishing the past bodde from a hypothetical, wrong bode.

bo vs leve — the great "live" split
This is the high-value distinction on the page. English "live" does double duty; Norwegian splits the labour between two verbs:
- bo = to reside — to have your home in a particular place. It answers Hvor? (where?). Jeg bor i Norge = "I live in Norway" (that's where my home is).
- leve = to be alive, or to live a life in some manner. It answers Hvordan? (how?) or speaks to existence. Jeg lever et godt liv = "I live a good life"; Bestemor lever fortsatt = "Grandma is still alive."
The test: if you could swap in "reside" in English, use bo. If you mean "be alive" or "live (one's life) in a certain way," use leve. Saying Jeg lever i Oslo sounds like you are making a dramatic statement about your existence rather than simply telling someone your address.

bo with i and på, and the housing idioms
bo almost always comes with a place expressed by a preposition — usually i or på:
- bo i
- cities, countries, enclosed places: bo i Oslo, bo i Norge, bo i en leilighet.
- bo på
- certain places, islands, institutions, smaller localities: bo på landet ("in the countryside"), bo på hotell, bo på Nesodden.
The choice between i and på follows the same patterns as place prepositions generally; it is partly idiomatic and worth learning place by place. A few housing idioms are also fixed units:
- bo sammen — to live together / cohabit (as a couple). De bor sammen = "They live together."
- bo til leie — to rent (live as a tenant), as opposed to eie (own). Vi bor til leie = "We rent."
- bo for seg selv — to live on one's own.
Vi har bodd sammen i tre år nå.
We've been living together for three years now.

Common Mistakes
❌ Jeg bode i Oslo i fjor.
Incorrect — Class 4 doubles the d: the preterite is bodde, not bode
✅ Jeg bodde i Oslo i fjor.
I lived in Oslo last year.
❌ Jeg har bod her i fem år.
Incorrect — the supine keeps both d's: har bodd, not har bod
✅ Jeg har bodd her i fem år.
I've lived here for five years.
❌ Jeg lever i Bergen.
Incorrect — for your address/residence use bo, not leve (which means 'be alive / live a life')
✅ Jeg bor i Bergen.
I live in Bergen.
❌ Bestemoren min bor fortsatt.
Means 'still resides' — for 'is still alive' use leve
✅ Bestemoren min lever fortsatt.
My grandmother is still alive.
Key Takeaways
- bo / bor / bodde / har bodd / bo! — weak Class 4, with the doubled -dde / -dd.
- Spelling trap: two d's in both past forms (bodde, bodd) — never bode / bod.
- bo = reside (answers where); leve = be alive / live a life (answers how, or existence).
- Pair bo with a place: bo i Oslo, bo på landet; learn bo sammen and bo til leie as units.
