If you copy this article to Word, you’ll already see that informations is not a word in English. The word information exists only in the singular (so only one, not many).
What happens when you copy the article into Word?
You’ll see a wavy red line under the word informations, right?
When you click on your right mouse button, the spell checker will suggest that you use the word information.
So there you have it. You cannot use information with an s at the end. So you can’t use it in the plural.
Information is just one of the words of which students of English often think that they can be used in the plural. But they can’t.
Some other words that you should be wary of not using them in the plural (so not with –s) are:
Oil gas petrol fuel
Hair (one hair is something you can count, so someone can have two hairs on their head, but otherwise hair is only in the singular).
Infrastructure (= the basic services in a society)
Do this exercise online here.
Fill in the right word. Only one word in the whole exercise is used in the plural. All the others are in the singular. Choose between:
knowledge, justice, furniture, information, weather, money, travel, hair, advice, evidence, infrastructure
