What does reaffirm mean?
Reaffirm means to confirm or state again something that has already been expressed, especially a commitment, belief, policy, decision, or promise. It is widely used in formal and political language, as when a government reaffirms its support for an ally or a leader renews a promise to the public. The word can also describe the simple repetition of an earlier assertion, though it often suggests deliberate renewal rather than an accidental repetition. Compared with affirm, reaffirm adds the idea of doing or saying something once more; compared with reassure, it focuses on confirming a position or commitment rather than easing someone's anxiety. Reaffirm is especially useful when a previously stated position must be made clear or renewed.

Where does reaffirm come from?
Reaffirm combines the prefix re-, meaning “again,” with affirm. Affirm comes through French from Latin affirmare, formed from ad- and firmus, meaning “firm” or “steadfast.” The prefix re- thus gives the modern verb its sense of confirming or renewing something previously affirmed. Its cognates in related Romance languages likewise express confirmation or affirmation.
