Saturated means holding as much dissolved substance as it can. A saturated solution, saturated ground, a saturated market.
Once a solution is saturated, adding more does nothing and the extra sits at the bottom — which is what the word means everywhere it is used. Saturated fats have no double bonds left to add hydrogen to. A saturated market cannot take another entrant. Note saturation, and the Latin for filling.
