Which word means to mix or combine something?

The word that means to mix or combine something is "blend." This term specifically refers to the act of thoroughly mixing various components to form a uniform mixture. In culinary contexts, for example, blending involves combining ingredients until they achieve a consistent texture and flavor, such as when making a smoothie or a sauce.

"Mingle" suggests a looser form of mixing, often used in social contexts rather than for combining substances. "Stir" refers to the action of moving something around to mix it but does not necessarily mean to combine different components into a uniform whole. "Combine" is a broader term that conveys the idea of bringing things together but does not inherently imply the thorough mixing that "blend" does.
