문화적 배경
This phrase is a cornerstone of Western investigative journalism and the legal system. It reflects a cultural emphasis on empirical evidence and the 'due process' of finding the truth before making a judgment. It became particularly popular in the mid-20th century with the rise of high-stakes corporate and political reporting.
The 'Into' Rule
Always try to use `into` after `investigation`. While `of` is technically okay, `into` sounds much more active and professional to native ears.
Don't Overuse It

What It Means
Imagine you lost your car keys. You don't just look on the kitchen table. You check under the sofa cushions. You look inside the fridge. You even check the pockets of the jacket you wore three days ago. That is a thorough investigation. It means looking at every tiny detail. You want to find the truth. You want to understand why something happened. It’s not a quick glance. It’s a deep, serious search for answers. It implies that no stone was left unturned. You are being 100% complete.
How To Use It
You usually put a strong verb before it. People often say conduct a thorough investigation into. You can also launch, initiate, or complete one. The word into is your best friend here. It connects the investigation to the topic. For example, you would say an investigation into the cause of the fire. It sounds very professional. It makes you sound like an expert who cares about facts. Use it when you have data or evidence to discuss. It’s a heavy phrase, so use it for heavy topics.
When To Use It
This is perfect for university essays or academic papers. It works great in business reports. Use it when talking about the news or legal matters. If a company loses money, they need this. If a crime happens, the police do this. It’s for serious situations where accuracy is the most important thing. It shows you are taking the matter seriously. It gives your writing a lot of authority. You will sound very smart in a high-level meeting. Just don't forget to actually have the facts to back it up!
When NOT To Use It
Don't use this for tiny, everyday problems. If you can't find your favorite socks, don't say this. It sounds way too dramatic. Don't use it with friends at a casual dinner. Saying "I did a thorough investigation into this pizza topping" sounds like a weird joke. Unless you are trying to be funny, keep it for professional or academic work. It’s too formal for a quick text message. Your best friend might think you’ve joined the FBI overnight.
Cultural Background
In English-speaking cultures, there is a high value placed on "getting to the bottom of things." This phrase comes from legal and scientific traditions. It’s about being fair, objective, and transparent. We see it in "True Crime" documentaries and investigative journalism all the time. It’s a part of a cultural obsession with justice and proof. It shows that we don't just accept the first answer we hear. We want the real, proven, documented answer.
Common Variations
You might hear a detailed inquiry into in British English. Some people say an in-depth analysis of in business. In science, they might say a comprehensive study. If you want to sound a bit more modern, you could call it a deep dive. All of these mean you are looking closely. However, thorough investigation is the most formal and serious version. It’s the "gold standard" for showing you did your homework.
사용 참고사항

The 'Sherlock' Effect
In English-speaking countries, using this phrase often makes people think of detective work. It carries a subtle vibe of 'uncovering a secret'.
