Today we answer a question from Morgan in China. Morgan writes: I have a question about the words "glad" and "happy." In which situations would I use them? I am confused by these words. Thanks so much. -- Morgan, China. Dear Morgan, Thank you for writing! First, let us take a look at the two words and see how they are the same and how they are different. "Glad" and "happy" both share the meaning of the feeling of pleasure, joy or delight. Sometimes the two words can be used the same way. In sentences with the words "be," "look" or "feel," "glad" and "happy" are very similar, so either one can be used.
