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.

Ludwig's WRAP-UP

In summary, the phrase "investigate about" is considered grammatically incorrect and should be avoided in formal English. As Ludwig AI points out, the correct alternatives are simply "investigate" or "investigate into", depending on the context. The rare occurrence of "investigate about" across various sources—including science, news, and wiki—underscores its non-standard usage. For clarity and correctness, opting for the standard forms is always advisable. While some occurrences can be found across different domains, its usage is highly discouraged in professional writing.

FAQs

How do I properly use the word "investigate" in a sentence?

Use "investigate" directly followed by the subject of the investigation (e.g., "The police will "investigate" the crime") or use "investigate into" (e.g., "They will "investigate into" the matter further").

What's a good substitute for "investigate about"?

Instead of "investigate about", try using just ""investigate"", "look into", or "inquire into" to maintain grammatical correctness and clarity.

No, "investigate about" is not grammatically correct. The correct usage is simply ""investigate"" or ""investigate into"".
