v. leached, leach·ing, leach·es
1. To remove soluble or other constituents from by the action of a percolating liquid: heavy rains that leached the soil of minerals.
2. To remove from a substance by the action of a percolating liquid: acids in groundwater that leach calcium out of the bedrock.
3. To empty; drain: "a world leached of pleasure, voided of meaning" (Marilynne Robinson).
To be dissolved or passed out by a percolating liquid.
1. The act or process of leaching.
2. A porous, perforated, or sievelike vessel that holds material to be leached.
3. The substance through which a liquid is leached.
