PED is often the answer to the crossword clues
[Walker, briefly] and [Disposable sock in a shoe store]
The answer TWOD is one of the weirder-looking answers in the cruciverse, but perhaps the place where it most makes sense.
Seen outside of crosswords as “2-D,” it’s short for “two-dimensional.” The adjective is most often used to describe geometric forms like squares and circles, which–unlike their 3-D (“THREED” in crosswordese) forms, cubes and spheres–lack depth. So TWOD is often described by clues like
- [Lacking depth]
- [Like line drawing]
- [Depthless, for short]
- [Less than solid]
- [One on a plane]
In everyday life, we’re most likely to experience TWOD things as the result of light, [Like most movies] that don’t require special glasses. Somehow, I’ve yet to come across a clue that refers to the most common 2-D sight: a shadow.
Whenever I come across TWOD, I can’t help but thinking of that slim (but not quite 2-D) novel, Flatland: A Romance of Many Dimensions
a satirical novella by the English schoolmasterEdwin Abbott Abbott, first published in 1884 by Seeley & Co. of London. Written pseudonymously by “A Square”,[1] the book used the fictional two-dimensional world of Flatland to comment on the hierarchy of Victorian culture, but the novella’s more enduring contribution is its examination of dimensions

However, there’s another TWOD object which should really be referenced in a clue for that answer someday:
