Tilde

The tilde is used in math to denote equivalence.

For some years now, Zamboanga has officially adopted the orthographic standard for their Chabacano: Spanish spelling for Spanish-derived words and native spelling for indigenous-derived words. Before this change, there was a flux between Spanish and native spellings for all words. Some Chabacano people still are not aware of the official decision. Punctuation and capitalization follow those of American English and Tagalog. Accents are not generally used, except for the tilde in Ññ, which, to Hispanics, is not a separate accent, but is part of the letter itself.

California, like several other states, prohibits the use of diacritical marks or accents on official documents. That means no tilde (~), no accent grave (`), no umlaut (¨) and certainly no cedilla (¸).

The tilde was used similarly in Portuguese on vowels to show that the letter bearing the tilde should be pronounced nasally.

swung dash A stock keyboard character, used in mathematics as the sign of similarity (a ~ b) and in lexicography as a sign of repetition. The same sign has been used in symbolic logic to indicate negation, but to avoid confusion, the angular negation symbol (¬) is preferred. Not to be confused with the tilde.
