An '''immersed submanifold''' of a manifold ''M'' is the image ''S'' of an [[immersion (mathematics)|immersion]] map ''i'': ''N'' → ''M''; in general this image will not be a submanifold as a subset, and an immersion map need not even be one-to-one – it can have self-intersections – so the term is used loosely.
