Other forms: rows; rowed; rowing
A row is a straight line of something, like a row of penguins at the zoo, tulips planted in a row in a garden, or a row of tuba players marching in the Fourth of July parade in your town.
A row is anything that's lined up, from the row of stitches on your knitting needle to the row of numbers on your spreadsheet. Row is also a verb meaning "to paddle." Row also means a noisy argument, but when you use it this way, it rhymes with cow, rather than toe. The origin of this last meaning is uncertain, but it probably came from the word carousal, or "drinking bout," as a kind of British university slang.
