En enkel guide til komma på dansk

(baseret på § 45–51 i Retskrivningsordbogen)

Der er næppe noget, der deler vandene i dansk skrift som kommaet. Nogle sætter for mange. Andre for få. Heldigvis følger kommaet nogle ret klare regler. Her får du den korte, brugbare version uden støj.

1) Vælg system – og hold fast

Der er to systemer:

  • Grammatisk komma (mest brugt)
  • Startkomma (komma før ledsætninger)

Det er valgfrit at sætte startkomma, men du skal være konsekvent i samme tekst. Guiden her tager udgangspunkt i grammatisk komma uden startkomma.

2) Opremsning

Komma mellem sideordnede led, hvor der kunne have stået og/men/eller.

Han købte kartofler, gulerødder og blomkål.
De grinede, råbte og løb.

Adjektiver: komma, hvis de er sideordnede:

en lille, idyllisk by
Ikke komma, hvis det første hører til helheden med det næste:
en lille fransk by

3) Selvstændige indskud

Komma omkring dele, der kan fjernes uden at ødelægge meningen:

Soldaterne havde, trætte og svedige efter marchen, lagt sig i grøften.
Den største danske å, Gudenåen, løber gennem Silkeborg.

Ikke komma, når udtrykket er nødvendigt for identifikation:

Den danske å Gudenåen løber gennem Silkeborg.

Også komma ved: tiltaleord (Kom herhen, Hans!), udråb (Øv, nu gik den i stykker!), forklaringer (bl.a., dvs., fx), og parentetiske relativsætninger (… som i øvrigt er helt normalt).

4) Helsætninger

Hvis du kan sætte punktum, kan du som regel også sætte komma.

Vinden peb, og tordenen rullede.
Hun glemte nøglen, så hun kunne ikke komme ind.
Regnen piskede, vinden peb, tordenen rullede.

Men ikke når der bare er to led i samme sætning:

Hun tog mig på ordet og kom dagen efter.

5) Ledsætninger

Ledsætninger kan ikke stå alene og begynder ofte med at, som, der, fordi, hvis, når, mens.

  • Slutkomma: der skal komma når ledsætningen slutter.
  • Startkomma: valgfrit. Vælg én praksis og hold den.

Jeg tror(,) at hun kommer, når hun har fri.
Han blev glad, fordi det endelig lykkedes.
Vi skal være klar, uanset om det regner eller ej.

Særlige placeringer kan flytte startkommaet (fx foran som/end, præpositioner og visse adverbialer). Hvis du ikke bruger startkomma, kan du som hovedregel ignorere de placeringstricks.

6) Komma foran men

Altid komma foran men mellem to helsætninger:

Han kom tidligt, men gik hurtigt igen.

Valgfrit når men forbinder ordled:

Hotellet var billigt(,) men elendigt.
Trætte, men lykkelige, kom de tilbage.

7) Små, men nyttige tommelfingre

  • Gentagelser: meget, meget glad.
  • Adresser/titler: Dansk Sprognævn, Adelgade 119 B, 5400 Bogense.
  • Inkvit (anførende): »Det er fint,« sagde hun.
  • Imperativer: Spis noget mindre, og dyrk motion.

8) Klassiske fejl – og hurtige fixes

A. Komma foran at i infinitiv
Nej: Jeg håber, at løbe i morgen.
Ja: Jeg håber at løbe i morgen.
(at løbe = navnemåden, ikke en ledsætning.)

B. Komma mellem subjekt og verbal
Nej: Peter, går i skole.
Ja: Peter går i skole.

C. Blandet praksis
Vælg startkomma eller ej – og hold fast.

9) Tydeliggørelse (§ 51)

Du kan sætte et ekstra komma for at gøre meningen klar eller undgå misforståelser:

De besluttede(,) straks at hæve prisen.
Han hvilede sig(,) lidt inden aftenens forestilling.
Han hvilede sig lidt(,) inden aftenens forestilling.

Men det bedste er ofte at omskrive, så meningen ikke afhænger af et enkelt komma:

De besluttede sig til straks at hæve prisen.
Lidt inden aftenens forestilling hvilede han sig.
Inden aftenens forestilling hvilede han sig lidt.

Praktisk råd: Hvis du kan høre to mulige betydninger, så omskriv. Klarhed vinder altid.

10) En lille praksis-guide

  1. Læs sætningen højt. Hør pauserne.
  2. Kan der stå punktum? Så skal der sandsynligvis et komma.
  3. Find ledsætningerne. Sæt slutkomma.
  4. Vær konsekvent med startkomma.
  5. Omskriv, når et komma alene bærer hele betydningen.

White Paper: “No-Nonsense B2B in the AI Era: The Path Forward for Marketing and Communication”

It’s been a long while since I wrote anything substantial – a bit of a contradiction, given that one of the best pieces of advice I ever got was: always share your knowledge.

So, here it is.

I’ve just finished a new white paper: “No-Nonsense B2B in the AI Era: The Path Forward for Marketing and Communication”.

It’s a thing I wrote as much for myself as for anyone else – a way to distill the key principles of my thinking based on many years of working with B2B companies across industries.

I might start writing more of these. There’s something valuable about pausing to reflect on what really works – and capturing it in a way that helps others too.

I want to say that this white paper is also an experiment. I want to see how white papers work these days – how much pull they create and who’s actually reading my work. That’s the main reason it’s behind a form.

Also, I’m more than happy to take feedback. Any kind. I imagine I’ll update the white paper later on as conversations and the market change.

A few notes:

  • This isn’t a practical guide with step-by-step instructions.
  • There are no visuals, no case studies, no marketing gloss.
  • It’s a strategic guide – a summary of the key approaches, ideas, and logic needed to create impact in a complex B2B world.

So what’s inside the white paper?

  • The role of communication and marketing in building trust – and why trust is still the bedrock of B2B relationships, even in the AI era.
  • Why strategy comes first – and how to build a core story that ties everything together.
  • How to choose tactics that resonate with your audience, including the right channels and formats.
  • The importance of pre-funnel engagement – educating and inspiring buyers before they even realize they have a need.
  • How to think about investment, data, and reporting – finding the sweet spot between resources, results, and trust.
  • When and how to use AI – where it helps, and where humans still matter most.
  • How trust, leadership, and culture shape every conversation, both inside and outside the company.
  • Why testing, learning, and optimizing matter – and how to keep improving in a world where change is constant.

If that sounds like something you’d like to explore, you can download the white paper here:

How Facebook, the company that said it wanted to bring the world together, became the great divider

Some of us are old enough to remember the halcyon days of social media, when we genuinely believed it would be a force for good in the world.

The early evidence was promising. There was the Arab Spring, in which citizens across the Middle East used Twitter and YouTube to organize mass demonstrations against oppressive regimes in their respective countries.

Wikipedia founder Jimmy Wales talks clickbait, fake news, the information wars and how to fix a broken internet

In this day and age of Trump, tech and anti-trust, it’s easy to forget the quiet Internet miracle that is Wikipedia. 

I will argue that Wikipedia – the no. 5 most visited website in the world – is the best thing on the Internet. It’s free, there are no ads, the knowledge is so vast, and it’s user-generated.  Continue reading “Wikipedia founder Jimmy Wales talks clickbait, fake news, the information wars and how to fix a broken internet”

Regenerative capitalism is coming: A conversation with former J.P. Morgan Managing Director John Fullerton

In 2001, John B. Fullerton decided to leave his high-paying, prestigious job on Wall Street. For almost 18 years, he had worked for the large American investment bank J.P. Morgan, including a long stint as Managing Director responsible for various aspects of the company’s global capital markets and derivatives businesses, and then ran the investment arm of LabMorgan. 

Today, John Fullerton still works with finance, but in a completely different way. He’s the founder and president of Capital Institute which is “a collaborative working to explore and effect economic transition to a more just, regenerative, and thus sustainable way of living on this earth through the transformation of finance.” Continue reading “Regenerative capitalism is coming: A conversation with former J.P.

Redefining the role of business: A conversation with Harvard Business School’s Geoffrey Jones

What will the future of business be like? One way of finding out is arguably to focus on future challenges in society at large. 

In 2017, Geoffrey Jones, professor in Business History at Harvard Business School, published Profits and Sustainability. In the opening lines, he wrote: “The degradation of the natural environment presents the greatest challenge faced by humanity.” Continue reading “Redefining the role of business: A conversation with Harvard Business School’s Geoffrey Jones”

What are the key lessons from business history that will remain important in the future? That’s the question I’ve been trying to answer in my recent posts.
