Tilde

Noun

1. A diacritical mark ⟨˜⟩ placed above a letter to modify its pronunciation. In Spanish, ⟨ñ⟩ is a palatalized ⟨n⟩, for example in ⟨cañón⟩. In Portuguese, ⟨ã⟩ and ⟨õ⟩ are nasalized vowels, for example in ⟨canção⟩. Another name for the Vietnamese tone mark dấu ngã, which is placed above a vowel to indicate a creaky rising tone (thanh ngã). Another name for apex, a curved diacritic used in the 17th century to mark final nasalization in the early Vietnamese alphabet. It was an adoption of the Portuguese tilde.
