Emphasize → It is formed from "em-" (a variant of "en-", meaning to cause to be in) and "phasize" (from Greek "phainesthai", meaning to show or to make known). The word means to cause something to be shown or made known more clearly or forcefully.
Think of 'showing' something more clearly ('phasize') and 'causing' it to be ('em-') — that's why emphasize means to make something stand out.
