Root, 3rd and 5th, stacked in thirds. The 3rd makes it major or minor; the 5th makes it diminished or augmented when it moves.
A slash names the bass
Chord/bass puts any note under a triad. A chord tone gives an inversion, such as C/E; another note gives a new chord: G/F is G7 with the 7th in the bass.
