From Wikipedia, the free encyclopedia
FYI is a common initialism of "For Your
Information" and "For Your own
interest".
FYI, short for 'For Your Information', is
commonly used in email or memo messages, typically as the first thing on the
subject line, to flag the message as an informational message. This
is typically used to mean 'For Your Information (Only)',
alternatively stated as 'Info Only', with the intent to communicate
to the receiver that 'action is not required'.
On the Internet,
FYIs are a subset of the RFC
series.
The following description is taken from FYI 1, the FYI on FYIs:
The FYI series of notes is designed to provide Internet users
with a central repository of information about any topics which
relate to the Internet. FYIs topics may range from historical memos
on "Why it was done this way" to answers to commonly asked
operational questions.
At the close of a recent cable describing the recovery of his
censor-held photographs of the fighting in the Holy Land, LIFE
Photographer John Phillips added the casual postscript:
"FYI, Burke narrowly escaped death outside
Jerusalem a few days ago."
Usage
notes
Although its usage long predates the internet and text messaging, FYI is
now probably used most frequently in electronic
communications.
