FWIW is an acronym for "for what its worth". It is used to preface a statement with a sense of "you may choose to ignore this, but Ill say it anyway". It can be used in many ways, such as to add information to a message or to inform someone of something that may or may not be useful. Here are some examples of how to use FWIW:

• "FWIW, I think your outfit looked cute today."
• "FWIW, Kiara told me the wedding invitations will be sent out Friday."
• "FWIW, the presentation didnt go as smoothly as they wouldve wanted".

FWIW can also inject a snarky tone into a statement, but usually, people use it to emphasize a key point or to politely disagree. It is important to consider the context when using FWIW, as with all electronic communication.
