How F augmented is built
F is the root, A the major third and C♯ the augmented fifth.
An augmented chord stacks two major thirds: the root, a major third (4 half steps up) and an augmented fifth (8 half steps up). The thirds split the octave into three equal parts, so F augmented uses the same keys as A augmented and D♭ augmented.
Every chord takes every other letter of the alphabet, so the letters of F augmented are F, A, C. That is why it is spelled F, A and C♯.
