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.
GmMaj11 is G, Bb, D, F#, A and C — GmMaj9 with the eleventh added on top.
It sounds dense and unresolved. Something is always omitted; the ♭3 and the natural 7 are what must not be.

Minor tonic — the melodic minor as far up as a guitar carries it.
Also written GmM11 or Gm(maj11). 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.
GmMaj11 has 3 of them, on strings 5-4-3-2-1 and strings 6-4-3-2-1, from the 3rd fret up to the 5th — every inversion the chord has: Bb in the bass, A in the bass and C in the bass. The one to learn first is the C shape at the 3rd fret, which is the easiest grip here.
Start with xx5576 — no barre and low, at the 5th fret. None of the shapes for GmMaj11 uses an open string, so every one of them is movable; the lowest sits at the 3rd fret. 4 of the 6 need a barre. Together they cover the neck from the 3rd fret to the 12th.
