FYI
for your information
What it means
FYI stands for 'for your information.' People add it to a message when they're passing along something useful that doesn't necessarily need a reply — a heads-up rather than a request. It's common in work emails and chats, where it can sound neutral and helpful or, depending on tone, slightly passive-aggressive.
