Engrossed → It is formed from "en-" (meaning to cause to be) and "gross" (from Old French *gros*, meaning large or thick). The word "engrossed" means to be fully occupied or absorbed in something, as if one is made large or thick with focus.
Think of being 'caused to be' ('en-') fully 'occupied' ('gross') in an activity — that's why engrossed means being completely absorbed in something.
