Expert writing Tips

Best practice

Always use the preposition "in" after "interested". The correct phrase is "is interested in". For example, say "She is interested in learning new languages" instead of "She is interested of learning new languages".

Common error

Avoid using "of" after "interested". The correct preposition is "in". Mixing up prepositions can change the meaning of your sentence or make it grammatically incorrect.
