Expert writing Tips

Best practice

Use "investigated" without the preposition "into". It's grammatically correct and widely accepted. For example, instead of "The police investigated into the matter", write "The police investigated the matter."

Common error

Avoid using "into" after "investigated". The verb "investigate" already implies a thorough examination or inquiry, making the preposition "into" unnecessary and grammatically incorrect.
