'information' as a plural noun

Many writers add -s to information by analogy with other languages or plurals. In standard English, information is a mass (uncountable) noun: don't write "informations."

Quick answer

"Information" is uncountable. Use "the information I..." or a quantifier/counter: "some information," "a piece of information," "three pieces of information."

Wrong: The informations I sent were incomplete.
Right: The information I sent was incomplete. - Or: Several pieces of information I sent were incomplete.
If you need plurality, use counters: pieces of information, items of information, bits of information, data points.

Core explanation: what uncountable means for "information"

"Information" names content or material you can't count directly without a counter word. Mass nouns don't take a plural -s and normally take singular agreement.

Say "The information is useful," not "The informations are useful."
To count, add a counter: "a piece of information," "three pieces of information."
Verb agreement: use singular with "information" (The information is ready). Use plural with counters (Three pieces of information were missing).

Grammar checklist: quantifiers, agreement, and counters

Quick checks: drop the -s, decide whether you mean a general amount or individual items, then choose a quantifier or a counter.

General amount → some information, much information, a lot of information, little information.
Counting → one piece of information, three pieces of information, several items of information.
Casual → info, bits of info.

Incorrect: There are many informations about the policy.
Correct: There is a lot of information about the policy.
Correct when counting: I found three pieces of information you need.

Real usage and tone: pick wording for work, school, or casual contexts

Match the form to your audience: formal writing prefers full phrases and precise counters; workplace writing values clarity and may use either form; casual speech accepts "info" and "bits of info."

Formal: "The information presented in Appendix B supports our conclusion."
Work: "The information I sent the client should answer their questions."
Casual: "Got any more info about the party?"

Work - Wrong: The informations I attached are confidential.
Work - Right: The information I attached is confidential.
School - Wrong: The informations in the lecture were dense.
School - Right: The information in the lecture was dense.
Casual - Wrong: All the informations I got were confusing.
Casual - Right: All the information I got was confusing. - Or: All the bits of info I got were confusing.

Memory tricks and quick tests

Use simple checks when you're unsure.

Mnemonic: If you can say "a piece of X," X is likely uncountable (a piece of information).
Replacement test: Swap "information" with "advice" or "water." If the sentence still sounds right without -s, treat the noun as uncountable.
Number test: If "three information" sounds wrong, switch to "three pieces of information."

Quick note: "a piece of information" not "an information."

Similar mistakes, spacing, punctuation, and hyphenation

Learners often pluralize other mass nouns by analogy (advices, furnitures). Fix them the same way: use quantifiers or counters.

Spacing: use normal spacing in phrases like "the information I received." Hyphens are only needed in compound modifiers before a noun (e.g., "well-researched information").

Wrong: I got many advices. -
Right: I got a lot of advice or several pieces of advice.
Wrong: I bought three furnitures. -
Right: I bought three pieces of furniture.
Note on data: technical writing may use "data are"; everyday usage often treats "data" as uncountable.
Wrong: I collected many datas for the project. -
Right: I collected a lot of data for the project. - Or: I collected several data points for the project.
Wrong: She gave me several advices. -
Right: She gave me several pieces of advice.
