Root, third and seventh: the guide tones fix the quality, so the fifth is dropped. That is what leaves a string free, so pick a tension to put on top.
Fmaj7 is F, A, C and E — F with the major seventh added on top.
It sounds lush, and only just resolved. The everyday tonic of jazz, bossa and neo-soul.

| F | A | C | E |

| 1 | 3 | 5 | 7 |
Tonic — a resting chord, but a soft one.
Also written FM7, FΔ7, FΔ, Fma7 or F major 7. The same chord either way; which spelling you meet depends on who wrote the chart.
Root, third and seventh. The third and seventh, the guide tones, are what make the chord major, minor or dominant, so the fifth can go: it says nothing the symbol needs.
Three notes means a spare string, which is the real point. Put a tension on it.
Fmaj7 has 6 of them, on the bottom three strings, the low-middle three, strings 6-4-3 and strings 5-3-2, from open position up to the 13th — all in one inversion, so the bass note never moves. The one to learn first is the F shape at the nut, which is the easiest grip here.
Start with xx3210 — no barre and 1 open string. 1 of the 9 shapes here sits in open position. 5 of the 9 need a barre. Together they cover the neck from the 1st fret to the 15th.
