Etymology
Origin of ingredient
First recorded in 1425–75; late Middle English from Latin ingredient- (stem of ingrediēns ), present participle of ingredī “to go or step into, commence,” equivalent to in- in- 2 + -gredient- “going”; see gradient
Explanation
An ingredient is one part of a mixture. For example, if you're making chocolate chip cookies, flour is just one ingredient you'll need. Ingredient comes from the Latin word ingredientem, meaning "that which enters into." It's not just for cookies. If you're in the lab mixing a chemical compound, you carefully add one ingredient after the next and record the results (and hope nothing blows up). It's also an element or factor of something, such as how that song you wrote has all the ingredients to be a sure-fire hit! Remember that it ends in -ent, since often what you Eat has ingrediEnts.
