Column (periodical)

A column is a recurring piece or article in a newspaper, magazine or other publication, where a writer expresses their own opinion in few columns allotted to them by the newspaper organisation. Columns are written by columnists.

What differentiates a column from other forms of journalism is that it is a regular feature in a publication – written by the same writer or reporter and usually on the same subject area or theme each time – and that it typically, but not universally, contains the author's opinion or point of view.
