Sove | Danish Grammar

Sove ("to sleep") is among the highest-frequency verbs you will ever use, and it hides a small but important irregularity: it is a strong verb that keeps its vowel o all the way through — sove, sov, sovet. English speakers, trained on the regular -ede pattern, instinctively want to say *sovede; that form does not exist. Beyond the conjugation, sove anchors a cluster of everyday expressions — oversleeping, sleeping in, falling asleep, wishing someone good night — that come up every single day.

Principal parts

Form	Danish	English
Infinitive	(at) sove	to sleep
Present	sover	sleep(s)
Past	sov	slept
Past participle	sovet	slept
Imperative	sov!	sleep!

💡

Sove is a strong verb with the o–o–o pattern: present sover, past sov (just drop the -er — no -ede!), participle sovet. The vowel never changes, which makes it one of the friendlier strong verbs. No agreement, as always — sover is the whole present (jeg sover, du sover, han sover, vi sover, de sover).

💡

The single most common learner error is regularising the past to *sovede. There is no logical shortcut: sove is strong, so the past is the bare sov. The perfect uses har: har sovet.

Present: sover

The present sover is identical for every subject.

Subject	Form	Example
jeg	sover	jeg sover længe i weekenden
du	sover	du sover godt
han / hun	sover	barnet sover endelig
vi	sover	vi sover med åbent vindue
de	sover	de sover til middag

Pssst, barnet sover endelig.

Shhh, the baby is finally asleep.

Jeg sover altid dårligt, når det er fuldmåne.

I always sleep badly when there's a full moon.

Past: sov

The past is the bare, strong sov — one short syllable.

Jeg sov som en sten i nat.

I slept like a log last night. (literally: like a stone)

Vi sov i telt, selvom det regnede.

We slept in a tent even though it was raining.

Present perfect: har sovet

The perfect takes har plus the participle sovet.

Har du sovet godt?

Did you sleep well? (literally: have you slept well)

Jeg har næsten ikke sovet hele ugen.

I've barely slept all week.

Past perfect: havde sovet

Hun var helt udmattet, fordi hun ikke havde sovet i to døgn.

She was completely exhausted because she hadn't slept for two days.

Sove over sig and sove længe: two kinds of late sleeping

Danish carefully distinguishes the accidental late sleep from the deliberate one, and English speakers conflate them. Sove over sig means to oversleep — to sleep past when you meant to wake up (a mistake). Sove længe means to sleep in / have a lie-in — to sleep late on purpose (a pleasure).

Undskyld jeg kommer for sent — jeg sov over mig.

Sorry I'm late — I overslept.

Om søndagen elsker jeg at sove længe.

On Sundays I love having a lie-in.

💡

Note the reflexive sig in sove over sig: it changes with the subject — jeg sov over *mig, du sov over dig, han sov over sig*. Forgetting the reflexive ("jeg sov over") leaves the phrase incomplete.

To say you fall asleep, Danish uses falde i søvn — note the noun søvn ("sleep"), which is spelled differently from the verb sove. Keep the two apart: sove is the verb, søvn is the noun.

Jeg faldt i søvn foran fjernsynet.

I fell asleep in front of the TV.

Børnene faldt i søvn med det samme.

The children fell asleep right away.

God nat and sov godt: bedtime phrases

The two fixed bedtime wishes are god nat ("good night") and sov godt ("sleep well") — the latter using the imperative sov.

God nat, skat. Sov godt.

Good night, love. Sleep well.

Common collocations and fixed expressions

sove over sig — to oversleep (by accident)
sove længe — to sleep in, have a lie-in (on purpose)
falde i søvn — to fall asleep
sove godt / dårligt — to sleep well / badly
sov godt — sleep well (the bedtime wish)

Sov godt, vi ses i morgen.

Sleep well, see you tomorrow.

A natural exchange

— Du ser træt ud. Har du sovet? — Næsten ikke. Jeg sov dårligt og faldt først i søvn klokken tre. — Av. Så må du sove længe i morgen. — Det kan jeg ikke, jeg sov over mig i går og skal nå toget.

— You look tired. Did you sleep? — Barely. I slept badly and didn't fall asleep until three. — Ouch. Then you'll have to sleep in tomorrow. — I can't, I overslept yesterday and have to catch the train.

Common mistakes

❌ Jeg sovede godt i nat.

Wrong past — sove is strong; the past is sov, never a regular -ede form.

✅ Jeg sov godt i nat.

I slept well last night.

❌ Jeg har sov dårligt.

Missing the participle ending — the perfect needs sovet, not the past sov.

✅ Jeg har sovet dårligt.

I've slept badly.

❌ Jeg sov over i morges.

Incomplete — sove over sig needs the reflexive pronoun matching the subject.

✅ Jeg sov over mig i morges.

I overslept this morning.

❌ Jeg faldt i sove.

Wrong word — 'fall asleep' uses the noun søvn, not the verb sove.

✅ Jeg faldt i søvn.

I fell asleep.

❌ Jeg vil gerne sove over mig på søndag.

Wrong sense — 'sleep in on purpose' is sove længe; sove over sig means oversleep by accident.

✅ Jeg vil gerne sove længe på søndag.

I'd like to have a lie-in on Sunday.
