To juxtapose two things is to put them next to each other, especially when they do not usually belong together. You do this so the pair can work on the viewer: people can compare them, feel a shock, laugh, or see a new idea that neither piece had alone. Painters juxtapose colours. Writers juxtapose a kind scene and a cruel one. A shop window might juxtapose a very old chair and a bright new lamp. This is not kitchen-table English. You meet it in essays, art class, film reviews, and other careful talk. Though actually, comparing is often why we juxtapose, not a second meaning of the word — the word itself is about the placing. If the two things always sit together in real life, this verb is probably too grand.
