affirmation is the act of affirming — asserting that something is true or confirming it — and the thing affirmed: a positive assertion.
The word entered English in the early fifteenth century from Old French afermacion and Latin affirmationem, from affirmare, built from ad ("to") and firmare ("to strengthen, make firm"), itself from firmus ("strong"). To affirm is literally to make something firm. In logic an affirmation is a proposition that asserts rather than denies, the counterpart of a negation. In law, from the 1690s, it names the solemn declaration made in place of an oath by those who conscientiously object to swearing — historically Quakers and Moravians — and a false affirmation carries the same penalty as perjury.
In everyday modern use the word most often means a short, positive first-person statement repeated to shape belief and behavior: "I am…" sentences said aloud each morning or written where they will be seen. Social psychology studies a related practice under self-affirmation theory, introduced by Claude Steele in 1988, in which reflecting on one's core values helps people absorb threatening information without becoming defensive.
An affirmation differs from an assertion, which simply claims something and may be disputed, and from a confirmation, which verifies something already proposed. The self-help sense keeps the root meaning intact: the statement is meant to make something firm by saying it.
Affirmations run through 📝My Boot Sequence, and I take the word literally: language makes things firm. It's why I'd rather be 📝Present In The Work — saying "I am working on" affirms that you are your work. Ordering every dish at 📝Cafe Gratitude as an affirmation helped inspire 📝Spirit Check.
