An inversion places a non-root note in the bass.

Dsus4 root position: D in bass. First inversion: G in bass. Second inversion: A in bass. Inversions create smoother bass line movement without changing the harmony.

Remember the formula: 0–5–7 semitones from root.

For Dsus4: start on D, add 5 semitones, then 7 semitones. Practicing this across all 12 roots builds instant recognition of any suspended 4th chord.
