Everyone is a writer. So why even ask this question if we all know what it means to write.
As a means of making our thinking public, writing can expose the beliefs and ideology of the author. The words committed to the page can have much greater impact than the writer may have intended. The care and concern needed to produce writing that accurately expresses ideas takes time and reflection.
Understanding how one’s own words will be interpreted by another person requires a good deal of thought and an ability to think as someone else. That skill is difficult to develop. Asking good questions about words, word combinations, and descriptors in text can be a good starting point in growing a sense of a third-party reader. Writing, then, is a much more profound activity than most of us realize.
