Vietnamese tilde

◌̃

1. A diacritical mark of the Latin script, called dấu sóng or dấu lưỡi câu in Vietnamese, and apex in Latin. Used to indicate the allophone of a syllable-coda /ŋ/, which is now spelled ng.

In Unicode, the perispomene ῀, called dấu ngã in Vietnamese and used as a tone mark, was misidentified as the tilde, conflicting with proper encoding of the dấu sóng. The two had different graphic forms when the Vietnamese Latin alphabet was created in the 17th century.

The tilde was most commonly used on the letters o and u, which triggered the allophone of a syllable-coda /ŋ/. However, it was occasionally used as an abbreviation of ng on the vowel letters ơ and ư as well, where it had the pronunciation .

The tilde (dấu sóng) and the perispomene (dấu ngã) could occur on a syllable together. When the vowel of the syllable was written with two letters, the perispomene tone mark would be placed on the first and the nasal tilde on the second. When they occurred on a single letter, the tilde was placed immediately above the letter and the perispomene above the tilde.

◌̃

1. A diacritical mark of the Latin script, called til (“tilde”) in Portuguese, and found on Ã/ã and Õ/õ.

• In the letter a, forms ã with the sound /ɐ̃/ followed by a semivowel or word-finally, as in avelã and canção, or in words derived from those, as in maçãzeira.
• In the letter o, forms õ with the sound /õ/ followed by a semivowel, as in canções and põem.
• Additionally, the same diacritical mark has had other uses in the past:
  • In the letter u, forms ũ with the sound /ũ/ followed by a vowel, as in hũa.
  • Abbreviation of m or n in the syllable coda, as in cõtãto (for contanto) and cõ (for com).
  • In the letter q, forms q̃ as an abbreviation of que and derivatives, as in q̃ for que, porq̃ for porque and paraq̃ for para que.
• The tilde can appear in nonstressed or stressed vowels alike:
  • A tilde can occur in an unstressed syllable in the same word as the acute or circumflex accent, as in sótão, órgão and bênção.
  • Multiple tildes can occur in augmentatives, as in aviãozão and leãozão.
  • In words with the suffixes -zinho (forms diminutives) and -mente (forms adverbs from adjectives, like the English suffix -ly), the stressed syllable changes and thus normally accents would be dropped, as in pé, pezinho; pálido, palidamente. That does not happen with the tilde: irmã, irmãzinha; alemã, alemãmente.
