Other forms: replenished, replenishing, replenishes
To replenish is to fill something up again. Stock back on the shelf, water back in the jug.
The word is formal and it suits supplies above all — replenish the stores, replenish stocks, replenish a glass. There is a pleasant use with people too, since a holiday can replenish you, and reserves of patience can be replenished. The noun is replenishment, which is common in retail and logistics. Its shape is worth noticing, being re- plus an old verb plenish, from the same root as plenty and plenary.
