One-dimensional
Two-dimensional (W3)
(E?)(L?) http://www.wsu.edu/~brians/errors/one.html
Once upon a time most folks knew that "three-dimensional" characters or ideas were rounded, fleshed out, and complex and "two-dimensional" ones were flat and uninteresting. It seems that the knowledge of basic geometry has declined in recent years, because today we hear uninteresting characters and ideas described as "one-dimensional". According to Euclid, no object can be one-dimensional (of course, according to modern physics, even two-dimensionality is only an abstract concept). If you are still bothered by the notion that two dimensions are one too many, just use "flat".
