A Clarification on something I thought I already knew... lol
Sus - Chords
Suspended second chords are inversions of suspended fourth chords, and vice versa.
For example, Gsus2 (G–A–D) is the first inversion of Dsus4 (D–G–A)
which is the second inversion of Gsus2 (G–A–D).
The sus2 and sus4 chords both have an inversion that creates a quartal chord (A–D–G)
with two stacked perfect fourths.
