Isomorphic → It is formed from "iso-" (from Greek "isos", meaning equal) and "morphe" (meaning form or shape). The word describes things that have the same form or structure, hence equal in shape.
Think of 'equal' ('iso-') shapes or forms ('morphe') when you hear 'isomorphic' — it means having the same form.
