Two corners of Danish punish the learner who pronounces words the way they are written: the big round numbers and the borrowed words. Both look intimidating on the page and both are spoken in clipped, reduced forms that you simply have to hear and copy. This page is about the sound of these words — how they are actually said in everyday speech — not their structure. (For where the vigesimal tens come from and how to build compound numbers, see the Numbers group.)
The tens 50–90: say the clipped form
Danish counts the high tens in twenties (a vigesimal system), and the written words for 50–90 are already abbreviations of much longer historical forms. In speech they reduce even further: the unstressed first part is swallowed, and the whole word lands as one or two quick syllables. Do not sound them out letter by letter.
| Number | Written form | How it's actually said |
|---|---|---|
| 50 | halvtreds | [halˈtʁas] — roughly "hal-TRAS"; the v is barely there |
| 60 | tres | [tʁas] — one syllable, "TRAS" |
| 70 | halvfjerds | [halˈfjæɐ̯s] — "hal-FYERS"; the d is silent |
| 80 | firs | [fiɐ̯s] — one syllable, "FEERS" |
| 90 | halvfems | [halˈfɛmˀs] — "hal-FEMS" |
halvtreds
fifty — [halˈtʁas], 'hal-TRAS'; not 'halv-treds' spelled out
tres
sixty — [tʁas], a single clipped syllable
firs
eighty — [fiɐ̯s]; the r colours the vowel, no spelled-out 'firs'
Compound numbers: units-first, run together
When you add a unit to a ten, Danish puts the unit first, joined with og ("and"): enoghalvtreds = "one-and-fifty" = 51. In speech the whole thing runs together as one word and the og shrinks to a quick, schwa-like [ɒ]/[ʌ]. Learners who pause between the parts sound robotic.
enoghalvtreds
fifty-one — runs together, roughly [enˀʌhalˈtʁas]; the 'og' is a tiny [ʌ]
toogtres
sixty-two — [toˀʌtʁas]; 'to-og-tres' said as one breath
femoghalvfems
ninety-five — [fɛmʌhalˈfɛmˀs]; one continuous word, not five chunks
Loanwords: half-French, half-foreign
Many everyday Danish words were borrowed from French, German or English and kept a pronunciation that breaks the normal Danish spelling-to-sound rules. They often have stress that an English speaker doesn't expect, plus nasal or heavily reduced vowels. The two failure modes are opposite: either you spell-pronounce them in a Danish way, or — for the English borrowings — you slip back into full English. Both sound off.
| Word | Meaning | How it's said | Watch out for |
|---|---|---|---|
| restaurant | restaurant | [ʁɛsdoˈʁɑŋ] | stress on the last syllable; nasal, no final t |
| garage | garage | [ɡaˈʁɑːɕə] | final -age is a soft [ɕ]-ish sound, stress on second syllable |
| computer | computer | [kʌmˈpjuˀtˀɐ] | roughly the English word, but with a Danish reduced final -er [ɐ] |
| weekend | weekend | [ˈwiˀgɛnˀ] | stress on the first syllable; final d is swallowed |
| fætter | (male) cousin | [ˈfɛtˀɐ] | æ vowel, fully nativised; not the English 'fatter' |
| chance | chance | [ˈɕɑŋsə] | soft [ɕ] start and a nasal vowel, not the English 'ch' |
restaurant
restaurant — [ʁɛsdoˈʁɑŋ]; stress at the end, nasal vowel, no audible final t
garage
garage — [ɡaˈʁɑːɕə]; the -age ending is a soft sound, not a hard 'g'
weekend
weekend — [ˈwiˀgɛnˀ]; stress on 'week', final d swallowed
fætter
cousin — [ˈfɛtˀɐ]; fully Danish vowel, don't say English 'fatter'
chance
chance — [ˈɕɑŋsə]; soft 'sh'-like start with a nasal vowel
The og is the giveaway
Of everything on this page, the reduced og in compound numbers is the detail that most separates fluent-sounding speakers from learners. Written out, toogtres contains the full word og, and the eye wants to give it weight. In speech it is almost nothing — a fleeting [ʌ] or [ɒ] with no stress, swallowed so completely that toogtres has the rhythm of a two-beat word, not a four-syllable one. English speakers, reading the og, tend to pronounce it as a clear "oh" or even "og", which immediately marks the number as read-aloud rather than spoken. The mental model that helps: treat the whole compound as one word with one main stress (on the ten), and let every other syllable lean toward a neutral schwa.
treoghalvfjerds
seventy-three — [tʁeˀʌhalˈfjæɐ̯s]; the 'og' is a vanishing [ʌ], stress on '-fjerds'
niogfirs
eighty-nine — [niˀʌfiɐ̯s]; two light beats then the stressed ten
How to learn the spoken forms
There is no rule that derives these pronunciations from the spelling, so the only reliable method is ear-first. Find a native recording (a phone-number readout or a price list works well), shadow it at half speed, and resist the urge to look at the written form while you do — the spelling will actively pull you back toward the wrong, sounded-out version. For the loanwords, the trap is the reverse for English borrowings: because you already "know" weekend and computer, your mouth defaults to full English. Deliberately Danicise the ending (a reduced -er [ɐ], a swallowed final d) and place the stress where Danish puts it.
Why this happens
Numbers and loanwords are both high-frequency words, and high-frequency words erode fastest in any language — speakers say them so often that they wear down to the shortest form that still communicates. That is why halvtreds is not pronounced like its spelling and why restaurant keeps a French shape: the spoken form froze at one stage while the spelling froze at another. There is no rule to derive these from; you learn them as fixed sound-objects, the same way English speakers know Wednesday is "Wensday".
Common Mistakes
❌ halvtreds said as 'halv-treds' letter by letter
Incorrect — spelling-pronouncing the number
✅ halvtreds [halˈtʁas]
Correct — clipped 'hal-TRAS'
❌ enoghalvtreds said in five separate chunks
Incorrect — pausing between unit, 'og', and ten
✅ enoghalvtreds [enˀʌhalˈtʁas]
Correct — one continuous word, 'og' reduced to a tiny [ʌ]
❌ restaurant with stress on the first syllable and a clear final 't'
Incorrect — Danish-spelling-pronouncing a French loanword
✅ restaurant [ʁɛsdoˈʁɑŋ]
Correct — end stress, nasal vowel, no final t
❌ weekend pronounced as the full English 'week-END'
Incorrect — Anglicising a nativised loanword (wrong stress, full final d)
✅ weekend [ˈwiˀgɛnˀ]
Correct — first-syllable stress, swallowed final d
❌ fætter said as English 'fatter'
Incorrect — using an English vowel for the æ
✅ fætter [ˈfɛtˀɐ]
Correct — Danish æ vowel, fully nativised
Key Takeaways
- The tens 50–90 are spoken in short, clipped forms; never sound them out by spelling.
- Compound numbers run together as one rhythmic word, with og reduced to a quick [ʌ].
- Loanwords keep odd stress and nasal/reduced vowels — and the English borrowings are nativised, so don't slip back into full English.
- These are all high-frequency words learned as fixed sound-objects, not derived from rules.
