(WAFF) - It's been called everything from a "twiddle" to a "squiggle."
Walmart associates have been known to call it a "squiggly," wiggling about when they call it out as part of a cheer that hearkens back to its use in the original wordmark (Wal~Mart).
The tilde is a versatile mark with different meanings and uses.
In Spanish and Portuguese languages, the mark is used above the letter 'n' to signify its pronunciation has an added 'yuh' sound. For instance, señor is pronounced "sen-yor."
Tildes have a designation in mathematics and geometry. In logic sequences, a tilde is used to indicate negation, and in mathematics, you would use the tilde to indicate an approximate value.
In music, you may see a tilde to indicate a weak pulse or a medium rhythm. And in the world of the Web, you may recall seeing tildes in some web addresses, particularly noting a user's home directory.
