Deeply → It is formed from "deep" (from Old English "deop", meaning profound or intense) and the suffix "-ly" (meaning in a manner of). The word "deeply" means in a profound or intense manner.
Think of something that is very 'profound' ('deep') and how it is done 'in a manner' ('-ly'). This helps you remember that 'deeply' means to do something in a profound way.
