part
'der Teil' and 'das Element' can both mean a component of something larger. 'Teil' is the normal, general word for a piece, section, or component. 'Element' often sounds a bit more precise or technical and means a basic part, for example in a system, list, or plan. Learners may confuse the words because both belong to a whole. In practice: for everyday things, 'Teil' is usually more natural; when you are talking about the basic building blocks of a structure, 'Element' fits better.
