Couplet

Definition:
In a poem, a pair of lines that are the same length and usually rhyme and form a complete thought. Shakespearean sonnets usually end in a couplet and offer a conclusion to a longer complex idea.

Example Poem:
"Love"

Love is not all: It is not meat nor drink Nor slumber nor a roof against the rain, Nor yet a floating spar to men that sink and rise and sink and rise and sink again.

Love cannot fill the thickened lung with breath Nor clean the blood, nor set the fractured bone; Yet many a man is making friends with death even as I speak, for lack of love alone.

It well may be that in a difficult hour, pinned down by need and moaning for release or nagged by want past resolutions power, I might be driven to sell you love for peace,

Or trade the memory of this night for food. It may well be. I do not think I would.

How The Couplet Is Used:
The couplet means that there are things in life other than love, but the author would not trade love for anything.
