Other forms: columnists
A columnist writes regularly for a newspaper or magazine, usually expressing opinions or commentary. A columnist might write an article endorsing a candidate for president one week, and a story about a terrible local fire the next week.
If you get a job as a newspaper columnist, you'll be expected to publish on a regular basis, maybe once or twice a week. An advice columnist answers letters that ask for help with personal problems and dilemmas, and a political columnist comments on various current events and political figures. The word columnist comes from a newspaper column, which got that name from the "vertical division of a page" meaning.
