Hi Temi Folorunsho

You can think of it like a Websters dictionary. It has all of the letters of the alphabet with all of the words & definitions. The words and definitions would be the values and the A, B, C, etc... would be the keys. Dictionaries only have one of each letter. If it had 2 M*s (duplicates), that would be confusing. But the letters *or keys can store many different words & definitions or values. 

dictionary = {"A": ['Airplane', 'Apricot'], "B": ['Book', 'Brain']}

Hopefully that visual helped :)
