A typical mistake non-native English speakers often make: using the word else instead of otherwise.

For example:

❌ If the weather is good, we’ll go for a walk, else we’ll stay inside.

It would sound much more natural to use otherwise:

✔️ If the weather is good, we’ll go for a walk, otherwise we’ll stay inside.

Else is mostly used in phrases like “someone else”, “what else”, “nothing else” etc.

✔️ Who else wants to play?

✔️ Open mind for a different view / And nothing else matters

Remember: English isn’t a C-like programming language!
