A rhyme is when two words sound alike, particularly in poetry when rhyming words are at the end of multiple lines. When similar sounds in multiples bound, that’s rhyme.
“True wit is nature to advantage dress'd; / What oft was thought, but ne'er so well express'd”: lines of rhyme written by English poet Alexander Pope. The way “dress’d” and “express’d” sound, that’s rhyme. Rhyme shares the same Latin root as rhythm, and poetry that rhymes does have a rhythm to it, like in a song. Rhyme is a noun for similar sounds or a poem that uses rhyme, and it’s also a verb, like saying, “What rhymes with orange?”
