An open string left ringing against a fretted grip. Because it costs no finger, it sounds a note the closed shape has none left for -- a tension on top, or a pedal root underneath. Either a familiar grip with open strings added, or a shape so sparse the open strings carry the chord. These belong to their key rather than to a shape, so D, A, G and E have many and Eb a handful.
Dsus2 is D, E and A — D with the third replaced by the second.
It sounds open, and neither major nor minor. With no third it works over either quality, which is why strummed parts lean on it.

| D | E | A |
|---|---|---|
| 1 | 2 | 5 |
Suspended — it hangs until something moves.
Also written D2 or D suspended 2nd. The same chord either way; which spelling you meet depends on who wrote the chart.
An open string left ringing against a fretted grip. It costs no finger, so it can sound a note the closed shape has none left for: a tension on top, or a pedal root underneath.
These belong to their key rather than to a shape: they cannot be moved up the neck. D, A, G and E have many; E♭ has a handful.
Dsus2 has 6 of them, on the top four strings, the bottom four strings, the middle four strings, strings 6-4-3-2, strings 5-4-3-2-1 and strings 6-4-3-2-1, from the 2nd fret up to the 5th — every inversion the chord has: D in the bass, E in the bass and A in the bass. The one to learn first is the D shape at the 2nd fret, which is the easiest grip here.
Start with xx0230 — no barre and 2 open strings. 1 of the 9 shapes here sits in open position. 4 of the 9 need a barre. Together they cover the neck from the 2nd fret to the 15th.

On Dsus2’s sound and use this page follows Robert Rawlins & Nor Eddine Bahha, Jazzology (Hal Leonard, 2005). The shapes and the derived voicings come from different places, and both are explained in where the chords and the theory come from.
