Technology and internet prepositions: On, at, in

You’ve probably studied the prepositions in, on, at, many times on your English learning journey.

Prepositions can be tricky for a variety of reasons. Many languages have equivalent prepositions to in, on and at, but they rarely work in the same way as in English. We also have many expressions that are a bit more figurative or abstract, which often go against the logic of preposition use.

When it comes to terms related to the internet and technology, we use the prepositions in, on and at, in different ways.

In this blog post, we’ll study how to use the prepositions in, on and at correctly in your English sentences.

At, on, in – the basics

First, let’s take a quick look at how to use these prepositions in regular situations. In general, we use ‘in’ for general areas and long time periods. ‘On’ is for more specific places, surfaces and days. Finally, ‘at’ is for specific places and specific times of the day.

Prepositions of place

Prepositions of place

Prepositions of time


We can use both ‘in and ‘onwith the word ‘car‘, so, it’s important to remember the difference. When something is inside the car we use ‘in‘. When something is on the surface of the car then we use ‘on‘.

Parts of day are normally preceded by ‘in‘. We get up in the morning and eat dinner in the evening. ‘Night‘ does not follow this rule. We say ‘I don’t like working at night‘.

When we use every, this, last and next before an expression of time, we do not use prepositions.

Can you think of any other important exceptions? Leave a comment below.

On, in, at with technology

We use the prepositions ‘in‘ and ‘on‘ a lot more than ‘at‘ when it comes to the internet and technology.

The word ‘online‘ already contains the preposition ‘on‘ within it. This is why we don’t use a preposition with the word. We also don’t use prepositions with the words ‘remote‘ and ‘remotely‘.

Hello, and welcome to the Intrepid English podcast. My name is Lorraine, and today, I have a conversation for you. My friend Alyssa is a Diversity and Inclusion Consultant in London.
