Plenitude
Etymology
From Latin plenitudo, "fullness," from plenus, "full" (also behind "plenty" and "replete"). It reached English through Old French. Unlike words for excess, plenitude keeps the wholesome sense of the Latin: a fullness that is complete and good rather than overflowing to a fault.
noun · /PLEN-ih-tood/
A state of abundance, fullness, or completeness — having plenty.
What it names
The condition of ample sufficiency and more, a rich fullness that satisfies without the negative charge of excess.
Example
The market in high summer was a plenitude of color — tomatoes, peaches, and peppers stacked in overflowing crates.
Related idea
Surfeit is fullness pushed past the point of comfort into too-much; plenitude is generous fullness that still feels like a blessing.
