Emotive language is where the author uses words or phrases to make the reader feel a particular emotion. When we discuss emotive language, we have to make sure that we identify the correct emotion. For example using phrases like, "The author uses emotive language language to make the reader feel sympathetic" or "The author uses emotive language to make the reader feel angry about the issue."
Think about what emotion you get from the following sentences:
Although you may have used different words to express each emotion, the emotions that the author has tried to present are as follows: 1) Sympathy and guilt, 2) Anger or a sense of 'injustice', and 3) Relaxation and well-being.
A good range of vocabulary (word choice) is useful when talking about emotive language, because simply saying 'happy' or 'sad' can sometimes make it hard to follow up with a good, detailed explanation. Whereas, if you said the text is trying to make the reader feel "excited", "nervous", or "relaxed", this gives you much more to talk about in your explanation.
