There are quite a few resources available for learning spoken Cantonese but i've found it difficult to find resources to learn Cantonese grammar.
For example, the sentence "he asked me to send you some photos" is, in my opinion, not a difficult sentence to translate in many languages but it seems particularly difficult in cantonese:
佢叫我 send的畫比你
keui yiu ngoh send dik waak bei nei
he + ask + I + send + of + photo + ? + you
I have found this is called the "passive voice" but i don't understand the sentence order or why/where this "bei" is used.
Does anyone have any good resources for learning cantonese grammar, especially making sentences?
Colloquial Cantonese writing tends to keep the pronunciation correct while the characters used vary. From your link about "畀" I can't find any references to "比".
I'm pretty sure I can figure out what the writer wants to express no matter which one is used, but it's hardly correct if "比" is used in my personal opinion.
Another thing to be aware of, it's rare (if not never) to replace "比" by "畀/俾".
From your link about “畀” I can’t find any references to “比”.
In this article (https://en.wiktionary.org/wiki/比) there is a box saying "For pronunciation and definitions of 比 – see 畀 (“(Cantonese) to give; for; to; by; etc.”).
(This character, 比, is a variant form of 畀.) "
Thanks for your info, but given this is near the end of the explanation of "比", this is probably rarely used. In fact, this usage gives me a feeling of being overly lazy or illiterate. My recommendation is to forget about this and use the other two when they're more appropriate.
Cantonese writings are not used in formal documents. In other words, we may say that all the Cantonese writings are colloquial, thus the mix use of those 3. One typical example is the subtitles in television. They're mostly formal Chinese; it's near impossible to find those 3 words there.
Not being rude to the native speaker you mentioned, but there's a significant amount of native speakers that can only listen/speak Cantonese. This is especially true in the mainland (Canton province). I'm also a native speaker and have been using Cantonese writing for more than 10 years, with handwrite IME in my phone.
I think I could be decent on answering questions about writing.
Here's some links from a quick Google on the 3 words.
