There are four compounds indicating consonants not used in the modern Vietnamese anymore:

  • tl: Indicate double consonants / tl / of the Middle Vietnamese. It was transformed into a consonant “p” of the modern Vietnamese.
  • bl: Indicate double consonants / ɓl / of the Middle Vietnamese. It was transformed into consonants “p”, “gi” of the modern Vietnamese.
  • ml: Indicate double consonants/ml / of the Middle Vietnamese. It was transformed into a consonant “nh” of the modern Vietnamese.
  • mnh: Indicates double consonants / mɲ / of the Middle Vietnamese. It was transformed into the consonant “nh” of the modern Vietnamese.

Four letters “f”, “j”, “w” and “z” are not part of the Vietnamese alphabet, now they are used in foreign loan words. They are all rooted in French, for example, “f” is from “effe” /ɛf/, “j” is from “ji” /ʒi/, “w” is from “double vé” /dubləve/, “z” is from “zède” /zɛd/.
The special digraph “gh” and the trigraph “ngh” are almost basically used before vowels of “i”, “e”, “ê”.
