A close-position chord with the second voice from the top lowered an octave. Sits on four adjacent strings.
Ebmaj11 is Eb, G, Bb, D, F and Ab — Ebmaj9 with the eleventh added — the note that fights the major third.
It sounds unsettled, and grittier than the rest of the major family. Most players drop the third or raise the eleventh instead, which is how you arrive at a sus chord or at maj7♯11.
Tonic, awkwardly — the eleventh sits a semitone above the third.

| Eb | G | Bb | D | F | Ab |

Also written EbM11, EbΔ11 or Eb major 11. The same chord either way; which spelling you meet depends on who wrote the chart.
Take the four notes stacked as close together as they go, then drop the second voice from the top an octave. The gap it opens is what makes the chord sound like a chord rather than a cluster.
It lands on four adjacent strings, which is why it is the workhorse voicing on guitar.
Ebmaj11 has 13 of them, on the top four strings, the middle four strings and the bottom four strings, from open position up to the 13th — every inversion the chord has: Eb in the bass, G in the bass, D in the bass and Ab in the bass. The one to learn first is the Eb shape at the nut, which is the easiest grip here.
5 of them sit on the top four strings, so you can run the inversions up one set without changing strings — which is the whole reason to learn them as a family rather than as separate grips.
Six notes and four fingers, so something has to go. Keep G and D (they fix the quality) and Ab and F (what the symbol is about). Let Bb and Eb go, in that order — a perfect fifth says nothing the root has not, and in a band the bass has the root.
Play Ebmaj11 as a shell — root, third and seventh — and the spare string takes the 13 (C).

How you get to it. The turn that lands on Ebmaj11 is Fm7 to Bb7 — the ii and the V of Eb — and Bb7 shares its third and seventh with Fm7, so the hand barely moves between them.
