I need more context to determine what you mean by “regel” and what language you’re using. Here are some possibilities:
- In Dutch, “regel” means “rule” or “line.”
- In German, “Regel” means “rule” or “regulation.”
- In Swedish, “regel” means “rule” or “line.”
- In Norwegian, “regel” means “rule” or “line.”
- In Danish, “regel” means “rule” or “line.”
If you could please provide more information, I’d be happy to help you find the four-letter word you’re looking for.
