Meaning

noun a formal expression by a meeting; agreed to by a vote

noun the ability of a microscope or telescope to measure the angular separation of images that are close together

noun the trait of being resolute

originRecorded since 1412, as Middle English resolucioun (“dissolution”), either from Anglo-Norman resolucion or directly from Latin resolūtiō (“a loosening, solution”), from resolvō (“to loosen”), itself from the intensive prefix re- + solvō (“to loosen”). By surface analysis, recognizably related to resolve and -tion.
