Shade and shadow look like the same idea. They’re not quite twins.

Stand under a tree on a hot day, and you’re in the shade, the cool patch where the sun can’t reach you. Step just outside it and you’ll see your shadow, the dark shape of you, stretched out on the ground.

One is the space. The other is the outline. English uses ‘shade’ for the general coolness and ‘shadow’ for the shape.

No rule to memorise. Just picture the tree. Shade is where you stand, shadow is what you cast.

Quick win: If you can point to its edges, it’s a shadow. If you can just feel it, it’s shade.

PS You can share shade with a stranger. You can only have your own shadow.

“He is in the home office” reads as fine English. It just doesn’t mean what you think it means.

In German, “Home Office” describes the whole activity of sitting at your kitchen table in slippers with your laptop open.

In English, “home office” is a room. In Britain, it’s also a government department, the Innenministerium, responsible for visas and immigration. Tell a Brit your colleague is “in the home office,” and they’ll assume he’s been called in about his visa.

This one’s a false friend, a word that looks familiar and behaves completely differently once it crosses the Channel.

You don’t need to feel bad about this one. Almost every German speaker reaches for it at least once.

Quick win: Swap “he’s in the home office” for “he’s working from home.” Same meaning, no immigration paperwork required.

Being too formal isn’t the problem. Not realising it anymore is.

At school, you may have learned sentences like: “I would be most grateful if you could kindly confirm.” It was correct. It still sounds correct. So it’s often the first thing that comes to mind.

That comes from how English was taught in Germany. School English followed the formal style that business culture used for a long time. International business English has since become more direct.

That doesn’t mean your English was wrong. It means you’re adjusting to the way people communicate today.

Take the Formality Quiz: eight short situations, no sign-up, about three minutes. It shows you where the old school habits still appear.

Quick tip: Choose your first instinct. The answer that feels slightly less polite is often the one people use now.

PS The problem isn’t that you’re polite. The problem is you’re still writing to a boss who retired in 2003.

We say “sorry” even when it’s clearly your fault.

Someone bumps into us. “Oh, sorry!” We apologise to inanimate objects. We apologise for existing. (I once apologised to a filing cabinet I walked into. It did not apologise back.)

It’s the sound British English makes before getting to the point.

You don’t need to take it personally, and you definitely don’t need to apologise back.

Quick win: When your British colleague says, “Sorry, but could I maybe add something?“, they’re not sorry. They just want to speak. Let them.

PS The average British person says sorry roughly eight times before lunch. Nobody involved has done anything wrong.

There’s a quirk I secretly love in my clients’ English. Capitalising every Noun in an email.

Meeting. Deadline. Attachment. They all want a capital letter in your head, whether English allows it or not.

German grammar is stubborn about this, and your fingers just do it, even after ten years here.

It’s proof your brain runs two grammar systems side by side, switching mid-sentence, without you noticing.

You don’t need to hunt down every capital letter before you hit send. Nobody reading your email in English has ever mistaken it for carelessness.

It’s not bad English. It’s bilingual autocorrect, and it’s German that’s winning.
