Line  A sequence of words printed as a separate entity on the page. In poetry, lines are usually measured by the number of feet they contain. The names for various line lengths are as follows:

monometer: one foot
dimeter: two feet
trimeter: three feet

tetrameter: four feet

pentameter: five feet
hexameter: six feet

octameter: eight feet

The number of feet in a line, coupled with the name of the foot, describes the metrical qualities of that line. See also end-stopped line, enjambment, foot, meter.
