water·er n.

Word History: Water is wet, even etymologically. The Indo-European root of water is *wed-, "wet." This root could appear in several guiseswith the vowel e, as here, or as *wod-, or with no vowel between the w and d, yielding *ud-. All three forms of the root appear in English either in native or in borrowed words. From a form with a long e, *wd-, which by Grimm's Law became *wt- in Germanic, we have Old English wt, "wet," which became modern English wet. The form *wod-, in a suffixed form *wod-r, became *watar in Germanic and eventually water in modern English. From the form *ud- the Greeks got their word for water, hud-r, the source of our prefix hydro- and related words like hydrant. The suffixes *-r and *-ros added to the form *ud- yielded the Greek word hudr, "water snake" (borrowed into English as hydra), and the Germanic word *otraz, the source of our word otter, the water animal.
