Etymology
Origin of affirm
First recorded in 1300–50; from Latin affirmāre, equivalent to af- af- + firmāre “to make firm” ( firm 1 ); replacing Middle English a(f)fermen, from Middle French afermer, from Latin
Explanation
To affirm something is to give it a big "YES" or to confirm that it is true. The verb affirm means to answer positively, but it has a more weighty meaning in legal circles. People are asked to swear an oath or affirm that they will tell the truth in a court of law. Lawyers may ask people to affirm facts, and judges may affirm rulings. In these cases, affirm means to verify or attest to the validity of something.
