Admiration is the feeling of liking and appreciating, like your admiration of your older sister. You ask her for advice and hope to be just like her when you are older.
The root of the word admiration is admire, which means "to regard with wonder or approval." People can receive admiration for many reasons, including their beauty, hard work, or intelligence. Often, there is a sense of gratitude or thanks when someone feels admiration. For example, your admiration for a favorite teacher includes an awareness of how much he or she helped you.
