Hi. Please help. I often get confused about the correct use of the phrases "is made up of" and "is made of." I think the phrase "is made up of" is the same (or very similar in meaning?) to the word "compose"; thus we can come up with the sentence like "Water is composed (is made up of) two hydrogen atoms and one oxygen atom.
But could you check these? Are they correct?
The sandwichis made up of / is made of two pieces of bread, a slice of salami, some sausage and a thick slice of tomato, and some lettuce, with dashes of mayonnaise, ketchup, and mustard.
Top answer
Both versions are correct. "Made up of" is sort of a fixed expression. "Made up from" is less common, but possible.

"Made from" is very common, but is more likely to refer to the material than to the components.
However, if you're talking about a "mixture," "made from" works.
