TILDES
The tilde diacritical mark (~) is very much associated with the Spanish language. We use the name “tilde” in English, taking that name from Spanish. Confusingly, the word “tilde” in Spanish is used more generally to mean “accent mark, diacritic”, of which a “~” is just one. What we call a “tilde” in English is usually referred to as a “virgulilla” or “tilde de la eñe” in Spanish.
