ingredient
Synonym discussion
Sense: noun/1
All three words refer to parts of a whole, but they differ in scope. An 'ingredient' is most specific to cooking — individual food items that are mixed together. A 'component' is a more technical word for one part of a machine, system, or process; it often implies that each part has a clear function. An 'element' is the broadest of the three and can refer to any basic part of something abstract, such as an element of style or an element of surprise. In cooking you would say 'mix the ingredients', not 'mix the components'. In engineering you would say 'electronic components', not 'electronic ingredients'. In writing you would say 'the elements of a good story', not 'the ingredients of a good story' (though 'ingredients' is used metaphorically for success).

Etymology
The word 'ingredient' comes from Latin 'ingredientem', meaning 'that which goes into' something. It is formed from the prefix 'in-' (into) and 'gradi' (to step or go). The original image is of something stepping into a mixture. English adopted the term in the 15th century, first as a cooking term for foods that go into a dish, and later expanding to metaphorical uses.
