Third-person singular present or plural form of 'blend,' meaning to mix or combine different substances or elements together.
From Middle English blenden, possibly from Old Norse blandi (to mix). The word has been used for centuries to describe mixing of liquids, colors, flavors, and ideas.
Blending is so ancient it predates chemistry: even medieval dyers 'blends' colors and bakers 'blends' flour, yet we rarely notice that the same word covers everything from smoothies to social mixing—showing how one word spreads across completely different fields.
