As a starting point for this post, let's take a look at the basics and consider individual components of 'to look into'.

Firstly, we have the super common verb 'to look', in the sense of directing our eyes in a direction in order to see something.

Secondly, we have the prepositional particle 'into', which I know from my experience with English learners is not the easiest preposition to understand. All you need to remember is that is describes a movement to an end point which is inside something.

So, when we use 'to look into' literally, it means to look with our eyes towards the interior or inside of something. The speaker is normally (but not always) on the outside or exterior.

We can look into anything that has a physical inside space, such as a house, a hole or a box.

Examples in context....

A robin was sitting on a tree and looking into my house.
The curious cat looked into the box as he knew a mouse was hiding inside it.

In addition to anything with an inside space, we can also use 'to look into' with all nouns with which we use 'in'. This includes anything that does not have a physical interior space, but with which we still use 'in', such as light, dark and the future.

When I looked into her eyes, I knew she was telling the truth.
Looking into the future, the outlook for treatment of the disease is very good.


It is common to combine 'to look into' with an additional preposition such as down, up or back, in order to add extra spatial information to what you are saying.

The additional particle needs to go between look and into, e.g. 'to look up into' or 'to look down into'.

A cat looking down into a pipe

Examples in context....

The cat is looking down into the drain.
She looked up into the night sky and was amazed by the amount of stars that she could see.
The scientist was looking down into the volcano.
I stood on my doorstep and looked back into my house one more time.


!!! Do not confuse 'look into' with 'look in' !!!

Due to their similarity and closeness in meaning it can be very easy to confuse these two phrasal verbs. In some situations this is not a problem because 'look in' can mean the same as 'look into' but 'look in' is used more commonly by native speakers to say that they are searching for something in a place or inside an interior space e.g. in a bag or a in a room.

Example in context....

LOOK IN: I can't find my keys! I've looked in my bag and in my room and they are definitely not there! INTENDED MEANING: I have searched for my keys in my bag and in my room and I am certain that they are not there.

In the above example, it would be incorrect to say "I've looked into my bag and my room" because this would only mean that you looked with your eyes and but did not search inside the room for the keys.


MEANING 2: To investigate (idiomatic)

CEFR Language Level

​B2 - Upper Intermediate



Transitive or Intransitive?

Intransitive (no direct object)



Potential Synonyms

To investigate

So now we come to the most common meaning of 'to look into', which means to investigate or to examine information about a particular situation or problem, in order to establish what caused it or what needs to be done to resolve it.

This is very common in business English when a problem has occurred and is also something that you may hear the police or other authority figures say when dealing with a problem.

Examples in context....

We promised the unhappy customer that we would look into the issue that they raised. INTENDED MEANING: We promised the customer that we would find out what caused the issue so that we can prevent it from happening again.
The school is looking into reports of bullying. INTENDED MEANING: The school has been informed that some students are bullying others and it is trying to establish if this is true and the details of the bullying.
The team of top scientists has been looking into the effects of climate change on biodiversity in the region and will publish their findings next week. INTENDED MEANING: The scientists have been working to understand what effects climate change has had on biodiversity in the region.

In terms of formality, I would say that 'look into' is less formal than 'investigate', however 'look into' is frequently used in business English for things such as establishing what has caused a particular issue to arise. 'Investigate' tends to be used by the police when or in large scale formal investigations, however it is normally possibly to use these words interchangeably without causing any problems.
