Etymology: "Rehydrating" is the present participle of "rehydrate," which is simply "re-" attached to "hydrate." The "re-" prefix comes from Latin and means "again" or "back," so rehydrating means putting water back into something that has lost it. The older part of the word runs back to Ancient Greek "hudor," meaning water, which also gave English "hydro-" in words like hydroelectric and hydrant. Greek "hudro-" was adopted into French and then into English as "hydr-," and English "hydrate" was formed from it with the Latin-derived ending "-ate," which in chemistry marks a substance combined with water. From there, "rehydrate" is a plain combination of two existing English parts.

Synonyms: restoring moisture, moistening
