Expert writing Tips
Best practice
Always use "investigate" or "investigate into" instead of "investigate about". The preposition "about" is unnecessary and grammatically incorrect in this context.
Common error
Avoid adding "about" after "investigate". It's redundant and creates an ungrammatical phrase. Instead, use "investigate" followed directly by the subject or "investigate into" for a more specific inquiry.
