Certain sounds possibly deserve their own letter in the alphabet, are there any indication that some more letter may be added to the English alphabet?
There have been plenty of proposals to extend or replace the English alphabet, including:
- Benjamin Franklin's phonetic alphabet
- Deseret alphabet
- Pitman's Initial Teaching Alphabet
- Romic alphabet
- Shavian alphabet
But plans? As Robusto pointed out, plans by whom? There's no Academy of the English Language.
If any letters got added to the English alphabet, they would arrive via popular usage, and would no doubt be resisted for a long time first.
But since orthography standardized in English (after The Great Vowel Shift and around the time of, and influenced by, publication of the King James Bible), the present alphabet became fixed.
You can read The BBC's history of letters being added to the alphabet. Their conclusion:
With the invention of J, the English alphabet now contained the 26 letters that we know so well. Other languages in Europe added accents to many letters to get extra sounds, for example á, Å and Ä but English has avoided this. There have also been attempts to revise the alphabet, introducing new letters to represent the ng sound, the ee sound and so on. All such attempts have so far been doomed to failure.
So it looks like we're stuck with A to Z.
If anything, we might expect to lose letters. Scrabble players excepted, I don't think many of us would miss Q and K that much, for example.
We have obviously lost letters in the past. Here are details of at least three such. As a minimalist, I do not mourn their passing
I suspect that people will just agree on a convention that a particular chinese sound is always written as XYZ - either just form popular use or perhaps because some foreign authority uses it.
New punctuation seems easier - there is the Interrobang a combined ? and ! (‽). You could argue that smileys have also done this to some extent.
There are two letters that could easily be removed from English. Q could be replaced by K. Qu could be replaced by Kw.
Replacing C would be only slightly more complicated. Cat becomes Kat. Place becomes plase. J is pronounced like the "s" in pleasure. Then we can combine dj for edj (edge), tj for itj (itch) and ch can be removed.
Dh could be used for dhe (as in the) to differentiate from th (as in thin).
The big challenge is to find another 11 letters for the vowels. Depending on dialect, spoken English has up to 16 vowels, but written English has only 5 letters for vowels.
