tildemerkintä
Tildemerkintä, also known as the tilde accent or tilde diacritical mark, is a diacritical mark used in various languages to modify the pronunciation or meaning of a letter. It is represented by the symbol "~" and is placed above or below the letter it modifies. The tilde is commonly used in Spanish, Portuguese, and some other languages to indicate nasalization of vowels. For example, in Spanish, the word "niño" (boy) is pronounced with a nasal "n" sound, while "niño" without the tilde is pronounced with a regular "n" sound. In Portuguese, the tilde is used to indicate nasalization in words like "ã" (a with a tilde), which is pronounced with a nasal "a" sound. The tilde can also be used in other languages to indicate specific phonetic or orthographic rules, such as in the Catalan language, where it is used to indicate the pronunciation of certain letters. Overall, the tilde is an important diacritical mark in many languages, helping to convey specific pronunciation and meaning.
