In defence of the semicolon – probably B2B’s least favourite punctuation mark

Kieran explains why the semicolon deserves your full support – and how to deploy it to (subtly) devastating effect in your B2B marketing copy.


In the world of B2B tech marketing, the semicolon often gets the fuzzy end of the lollipop.

I’ve seen countless brand style guides that either ban the poor punctuation mark outright, or warn adventurous writers against daring to use it in their copy. The guides invariably justify this stance with the claim that, because no sentence absolutely demands you use a semicolon, it’s simpler never to use them at all.

And it’s true: there’s always* another punctuation mark that could do much the same job – be it a comma, or a full stop.

But there’s the rub. ‘Much the same’ isn’t the same.

OK. What can the semicolon do for me?

The semicolon grants you the power of nuanced expression. It lets you keep two ideas separate, while signalling that a strong link exists between the two.

It also grants you the power of overt erudition – which, if you’re writing for the scholarly brand, might be exactly what you want.

How do I wield the semicolon to (subtly) devastating effect?

The semicolon has one primary use: to join two complete sentences into a single sentence when…

  • You feel those sentences are so closely related, a full stop seems too strong a break
  • You shouldn’t, in fact, be using a comma or a colon instead

Here’s an example:

“We launched our first SaaS solution in 2012; we achieved world domination in 2013.”

That semicolon signals the world domination was directly linked to the SaaS launch. Now, you certainly can use as full stop instead, and trust the reader to make the logical leap themselves…

“We launched our first SaaS solution in 2012. We achieved world domination in 2013.”

…but the result is blunter and brasher. It’s more forceful, but less thoughtful.

We’ve lost that extra nuance.

Wow. I want to truly master the semicolon. Where can I learn more?

I taught myself to use the semicolon with the help of the Penguin Guide to Punctuation. It’s a delightfully lean volume, enlivened by flashes of archness from its writer, Larry Trask. Even better, its contents are publicly available on the University of Sussex’s website.

I’ll leave you a final tip, direct from Larry, on best-practice semicolon deployment:

“In any case, don’t get into the habit of using a semicolon (or anything else) merely to mark a breathing space. Your reader will be perfectly capable of doing his own breathing, providing your sentence is well punctuated; punctuation is an aid to understanding, not to respiration.”

*Except in some, very special, circumstances. 😉
