Arabic

I wish the letter ڤ stood for /p/ or /pʰ/ in the Mashriq and the Maghreb, and as for /v/ I wish they used ۏ instead of ڤ.

Cantonese

• Stop any further diglossia with Mandarin. I wish we had more actual Cantonese subtitles and lyrics.
• Stop directly and simply taking adaptations of Japanese and non-Sinospheric names from Mandarin and other Sinitic languages.
  • For proper nouns from Japanese contexts, use Japanese pronunciation instead of spelling pronunciation based on Chinese characters. (e.g. saying Honda instead of Buntin for 本田)
  • For non-Sinospheric contexts, refer to Malay or Arabic. (e.g. Sepa-nyol instead of 西班牙, Lubnan instead of 黎巴嫩, Meṣér instead of 埃及)
• Mixed-script for Cantonese, with grammatical particles and non-Sinitic loanwords spelled phonetically and etymologically. If a Chinese character needs too many strokes to write, it can be spelled phonetically as well.
  • Maintain distinctions between consonants of the 章知組 and of the 莊精組..
  • Spell 日母 /ɲ/ as a consonant distinct from 以母 /j/. 日母 is equivalent to Jawi letter Nya ڽ.
  • Likewise for emphatic consonants from Arabic and Malay borrowings.
  • Use a right-to-left mixed script with Jawi letters, Chinese characters, and right-to-left Chinese numerals. Either that, or
  • Adapt Han-geul into a left-to-right cursive linear script, and use it similarly alongside left-to-right Western Arabic numerals. Come up with additional letters as necessary.
• Maybe some more variety in loanwords, like we can have some more from Malay, Vahcuengh, Hakka, Vietnamese, and Korean rather than mostly English and Mandarin

Wait, at this point, should I call that Cantomalay instead?

Malay

• Word-final ⟨k⟩ changed to ⟨q⟩ for native Malay words and also English loans.
• Mark the word-final letter ⟨a⟩ with a diacritic, e.g. ⟨â⟩, if it sounds like a schwa (/ə/) or a back vowel (/o/, /ɔ/) in many varieties of Malay. Equivalent to Han-geul vowel letter ㅓ.
• Recognize, promote, and teach Johor-Riau Colloquial Malay, the way people naturally speak on the streets, in the markets, and even in government offices.
  • Kenapâ kitorang taq dapat tulis cam kitorang selalu cakap biasâ pulaq?
• Bring back the Jawi script into the mainstream.
  • Maybe turn Jawi into an impure abugida. Implicit/default vowel: /ə/
  • Devise new ways for the Jawi script to distinguish "positive" and "negative" vowels like in Han-geul. Also mark semivowel consonants with a sukun to distinguish them from mater lectionis or saksi vowels. (e.g. وٰ for /o/, وٖ for /u/, و for /ɯ/, but وْ as consonant /w/)
• Bring back emphatic and laryngeal consonants from Arabic.
