Macaronic verse mixes words, phrases, or whole lines from two or more languages in a single poem. The languages may be blended for comic effect, learned display, satire, or emphasis, and one language is often dominant while the other appears in scattered insertions or alternating passages. In older poetry, Latin commonly appears alongside the vernacular.
Example
Good morrow, friend, how bright the day,
mais le vent calls me on my way;
I take my cloak, and, as I go,
I whisper, gracias, to the snow.
