"Informations" or "information"?
I need some informations.
I need some information.
The rule
"Information" is uncountable — it has no plural and takes no "a/an." Say "some information" or "a piece of information," not "informations."
Some English nouns are uncountable: you can't count them one by one, so they have no plural "-s" and don't take "a / an." "Information" is one of them — along with advice, news, furniture, and luggage.
To talk about an amount, use words like "some," "a lot of," or "a piece of."

How to remember it
information, advice, news, furniture, luggage — all uncountable. No "-s," no "a/an." Use "a piece of" when you need to count them.
Frequently asked
Why can't I add "-s" to information?
Because it's uncountable — it names a mass, not separate items. Like "water" or "music," it has no plural. Use "some information" or "pieces of information."
What are other common uncountable nouns?
advice, news, furniture, luggage, equipment, homework, progress, and knowledge — none of these take a plural "-s" in standard English.
