English has one workhorse intensifier — very — and a pile of colourful alternatives (incredibly, super, dead, mega). Dutch is the same in shape but the choices are sharply register-coded, far more than in English. Saying something is zeer interessant sounds bookish and formal; hartstikke interessant sounds like a friend on a café terrace; mega interessant sounds like a teenager. Get the intensifier wrong and you don't make a grammatical error — you misjudge the social temperature of the room. On top of the free-standing intensifiers, Dutch has a productive and delightful system of intensifying prefixes (dood-, peper-, stom-, bloed-) that glue onto an adjective to crank it to the maximum: doodmoe (dead tired), peperduur (ridiculously expensive). This page maps the whole scale from formal to slang and shows where each piece belongs.
The neutral core: heel, erg, zeer
Three words cover "very" in the unmarked middle, and they are not interchangeable.
- heel — the everyday default, neutral, spoken and written: heel mooi, heel veel. When it modifies an adjective it can agree like an adjective (een hele mooie dag) in informal use.
- erg — also neutral, leaning slightly informal-spoken; literally "badly/seriously", so it pairs naturally with both good and bad things: erg leuk, erg jammer.
- zeer — the formal/written one. In speech it sounds elevated or earnest; in writing it is the standard intensifier of careful prose. Zeer also still means "sore/pain" (het doet zeer), a separate word.
Het was een heel leuke avond, dank je wel.
It was a really nice evening, thank you. (heel — neutral, everyday)
Wij zijn zeer verheugd u te mogen verwelkomen.
We are very pleased to be able to welcome you. (zeer — formal, written register)
Dat is erg jammer, ik had je graag gezien.
That's a real shame, I'd have liked to see you. (erg — neutral-informal spoken)
The informal layer: hartstikke, ontzettend, enorm, reuze
Step down into casual speech and a richer set opens up. These are warm, expressive, everyday-spoken — fine in chat and conversation, out of place in formal writing.
- hartstikke — the quintessential Dutch informal intensifier, untranslatable but roughly "totally/really": hartstikke leuk, hartstikke goed, hartstikke bedankt. (Literally "heart-stuck"; don't analyse it, just use it.)
- ontzettend — "tremendously", strongly emphatic, slightly more written-friendly than hartstikke but still expressive: ontzettend moe, ontzettend lief.
- enorm — "enormously", versatile, mildly informal: enorm blij, enorm veel werk.
- reuze — "giant-", older and a touch dated but warm: reuze gezellig, reuze bedankt.
Ik vond het hartstikke gezellig vanavond, echt.
I had a really lovely time tonight, honestly. (hartstikke + echt — warm, informal)
Ze was ontzettend lief voor me toen ik ziek was.
She was incredibly sweet to me when I was ill.
Dat scheelt enorm, bedankt!
That helps a huge amount, thanks!
The slang/youth layer: mega, super, kei-, knal-
The most informal free intensifiers are loans and youth slang. They are perfectly current but firmly casual — and some are regionally marked.
- super — "super-", attaches to almost anything: superleuk, super blij. Borderline between informal and neutral now, but still too light for formal prose.
- mega — "mega-", emphatic youth/casual: mega vet, mega irritant.
- kei- — (regional: southern Netherlands / Brabant) literally "boulder-", glued on: keileuk, keigoed, keihard (the last one, "rock-hard", is standard everywhere). Heard nationally now but flavoured southern.
- knal- — "bang-", informal, often for colours and impact: knalrood (bright red), knalhard.
Die film was echt mega goed, moet je zien!
That film was seriously mega good, you've got to see it!
Het was keileuk om jullie weer te zien.
It was great to see you all again. (kei- — informal, southern-flavoured)
Intensifying prefixes: the productive system
Here is where Dutch outdoes English. A small set of nouns and adjectives function as intensifying prefixes that fuse onto an adjective to mean "maximally". They are written as one solid word — no space, no hyphen — and the prefix usually carries its own literal image that you can feel:
| Prefix | Literal sense | Example | Meaning |
|---|---|---|---|
| dood- | death- | doodmoe, doodeng, doodziek, doodsbang | dead tired, terrifying, deathly ill, scared stiff |
| peper- | pepper- | peperduur | ridiculously expensive |
| stom- | dumb- | stomvervelend, stomverbaasd, stomdronken | deadly dull, dumbfounded, blind drunk |
| bloed- | blood- | bloedheet, bloedserieus, bloedmooi | boiling hot, dead serious, stunning |
| poep- | poop- (slang) | poepsimpel, poepduur | dead easy, dirt expensive |
| spuug- | spit- | spuugzat, spuuglelijk | sick to death of, hideously ugly |
These are informal but vivid, and very common in speech. Doodmoe and peperduur are near-universal; spuugzat ("spit-sated", i.e. utterly fed up) is strong and colloquial; bloedmooi ("blood-beautiful", i.e. gorgeous) is a compliment.
Na die dienst was ik doodmoe en wilde alleen maar slapen.
After that shift I was dead tired and just wanted to sleep.
Die nieuwe telefoon is echt peperduur, niet te betalen.
That new phone is ridiculously expensive, unaffordable.
Ik ben het gezeur nu echt spuugzat.
I'm absolutely sick to death of the moaning now. (spuugzat — strong, colloquial)
'Veel te' — far too
For "too" Dutch uses te; for "far too / way too" it stacks veel te ("much too"). This is a different axis from "very" — te means the quantity has passed an acceptable limit, not merely that it is high.
Deze koffie is veel te sterk voor mij.
This coffee is far too strong for me.
We zijn veel te laat vertrokken, sorry.
We left way too late, sorry.
Don't confuse heel/erg ("very", a high degree) with te ("too", over the limit): heel duur is "very expensive" (maybe fine), te duur is "too expensive" (a dealbreaker), veel te duur is "way too expensive".
Common Mistakes
❌ (Formal report) De resultaten zijn hartstikke goed en mega belangrijk.
Wrong register — 'hartstikke' and 'mega' are casual-spoken; a formal text needs 'zeer' or 'bijzonder'.
✅ De resultaten zijn zeer goed en bijzonder belangrijk.
The results are very good and particularly important. (formal intensifiers)
❌ (Casual chat to a friend) Dat was zeer leuk, dank je.
Off-register — 'zeer' sounds stiff/earnest among friends; casual speech wants 'heel', 'echt' or 'hartstikke'.
✅ Dat was echt heel leuk, dank je!
That was really nice, thanks!
❌ Die jas is peper duur.
Wrong spelling — intensifying-prefix compounds are written solid: 'peperduur', not as two words.
✅ Die jas is peperduur.
That coat is ridiculously expensive.
❌ Ik ben heel moe na de reis — ik kon niet meer lopen.
Under-strength for the meaning — if you literally couldn't walk, you want the maximal 'doodmoe', not the neutral 'heel moe'.
✅ Ik was doodmoe na de reis — ik kon niet meer lopen.
I was dead tired after the trip — I couldn't walk any more.
❌ Deze soep is heel te zout.
Wrong — you can't stack 'heel' onto 'te'. For 'far too' it's 'veel te': 'veel te zout'.
✅ Deze soep is veel te zout.
This soup is far too salty.
Key Takeaways
- The neutral core is heel (everyday), erg (neutral-spoken), zeer (formal/written) — match it to register; zeer for formal prose, heel/echt for casual speech.
- Informal speech adds hartstikke, ontzettend, enorm; slang/youth adds super, mega, and regional kei- (southern) and knal-. None belong in formal writing.
- Intensifying prefixes (dood-, peper-, stom-, bloed-, spuug-) crank an adjective to the maximum and are written solid as one word: doodmoe, peperduur, stomvervelend, spuugzat.
- veel te = "far too" (over the limit), a different axis from "very" — don't stack heel onto te.
