for your information
Meaning
Used to tell someone something they should know; often a preface to a fact, sometimes with a mildly annoyed or corrective tone.
Origin
A literal phrase meaning “for the sake of your knowledge.” It became a common set expression in letters and formal communication, later spreading to speech as FYI.
Notes
Neutral in writing (“FYI”), but in speech it can sound sharp or corrective (“For your information, I already did”). Tone matters.
