FYI stands for For your information, an email and office abbreviation.
Flags that a message or attachment is being shared for awareness only, with no reply or action expected. It is one of the most common subject-line and opening tags in workplace email, memos and chat.
Example: FYI, the parking garage will be closed for resurfacing all day Friday.
Usage notes
Usually written in capitals without periods; F.Y.I. appears in older memos. Communication coaches warn that a bare "FYI" forward can read as curt or passive-aggressive, so adding a line of context helps. It contrasts with FYA ("for your action"), which does call for a response. As a noun, "an FYI" means a brief informational note.
