Etymology

Origin of glue

1300–50; (noun) Middle English glu, gleu < Old French glu < Latin glūt- (stem of glūs ); cognate with Greek gloiós gum, anything sticky; (v.) Middle English glywen, glewen, derivative of the noun

Explanation

Glue is a liquid adhesive, used to stick two items together. A little kid may use Elmer's glue to decorate an art project, and you may use Krazy Glue to repair a mug's broken handle. Whatever the case, you hope the glue sticks. Most glue comes in a squeeze bottle and is used in small drips and lines to paste one material to another, but some glue comes in solid sticks that aren't as messy. When you stick one thing to another with glue, you glue it. The Old French source of glue is glu, from the Latin gluten, which means both "glue" and "beeswax."
