Other forms: diversifications
Diversification is the opposite of sameness. Use diversification to describe the goal achieved by a store that started with deli sandwiches and now offers gourmet coffee, muffins, soups, and salads.
If a group seeks diversification, it wants to attract people of different ages from various backgrounds. If your financial adviser tells you that your stock portfolio needs diversification, this means you need to have stocks from a variety of companies and different industries. In other words, things should be more diverse. Use that to remember how to pronounce the word: Say diverse, then add if-ick-a-shun.
