Yeah.

I speak four languages on a semi-daily basis. It's almost impossible to avoid the occasional flub without a spell checker.

Matelas, matras, matratze, and mattress.

Another one is succes, success, succès. No success without the SS in English.

There's also occasional, ocasional, occasioneel, and occasionnel. Read stuff like that too much and your eyes go wonky.

The comma rules are also subtly different. At least I think they are. I've given up caring.

Weirdly, I get its/it's right more often than monolingual English speakers. Dutch has a thing where sometimes the plural is denoted with a 's. The greengrocer's apostrophe it's sometimes called in English when you make that mistake.
