Etymology

Origin of hem¹

First recorded before 1000; Middle English hem(e), Old English hem, probably akin to ham “piece of enclosed land, enclosure”; home

Origin of hem²

First recorded in 1520–30; imitative

Explanation

When kids grow taller, their parents sometimes have to let out the hem in their pants so they'll be long enough. The hem is the very bottom, folded edge of a piece of clothing. Most of your clothes have at least one hem in them — at the ends of your sleeves, the bottom of your skirt, or along the edge of your t-shirt. When a person sews a hem, whether he's making a dress or a pair of curtains, he folds a very small amount of fabric under two or three times and stitches along the edge in a straight line. In Old English, the word hem means "a border."
