Think of a smile – does it just peek? Or shine so brightly, wonderfully sleek? "Greatly" adds emphasis, you understand, To show how much something fills your hand. Like saying "I enjoyed that play," with glee! You could say “I enjoyed it greatly ,” you see! It’s more than just a little bit, my friends, It's a feeling strong, that never ends...
