Faith is a belief without evidence. If one had sufficient evidence to warrant belief in a particular claim, then one wouldn’t believe the claim on the basis of faith. "Faith" is the word one uses when one does not have enough evidence to justify holding a belief, but when one just goes ahead and believes anyway.
For example, let's assume Jesus existed and was buried in a tomb. One can believe the corpse was missing for any number of reasons, like one can believe the body arose from the dead and ascended to heaven, one can believe aliens took the body in their spaceship, or one can believe a ghost haunting the tomb merged with the corpse and animated it. Belief in any of these claims would require faith because there’s insufficient evidence to justify any one of these particular options. Belief in any of these claims would also disregard other, far more likely possibilities - for example, that the corpse was stolen, hidden, or moved.
If one claims knowledge either in the absence of evidence, or when a claim is contradicted by evidence, then this is when the word "faith" is used. "Believing something anyway" is an accurate definition of the term "faith."

teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
