Probably some other cases too, and im not sure which one applies to the specific sound you’re struggling with but a couple of examples
A recent example I came across while doing Vietnamese vocab was several letters being used to make an “Z” or “L” sound in some cases. For compound sounds, there are things like “ng” sounding like an “M” in front of words sometimes in Vietnamese or in English we have things like “th” or “ch” where the resulting sound doesn’t sound like it comes from either of the building blocks. “T” is pronounced like “tuh” and “H” is pronounced “huh”, (there is a certain irony in trying to use letters to communicate the pronunciation of letters, but whatever.) so you’d think that “th” would be something like “tuh huh” instead of the actual pronunciation. While I was writing this I thought of an example where this is how it works: “tw” gets pronounced like “twuh” like in “twelve” or “twenty”… and then I remembered “two” exists and sounds like “too” (and “to”) for some reason. So yeah. It’s really hard to come up with a consistent rule for a lot of these.
EDIT: Oh I just remembered another funny exception for “ch”: In “Chemistry” the “H” is neither pronounced nor does it modify the “C” to make the normal “ch” sound. It just sounds like there is a “C” there. Like “Cemistry.” Except looking at that, that pattern is used in something like “Cemetery” and then the “C” sounds like an “S”. I’m going to stop now because there are so many of these I could probably go on forever if I kept thinking about it.



Oh I didn’t know the current alphabet came from the Portuguese. I assumed it was from the French when they colonized Vietnam.
The point about the logographic characters being distinct is interesting. I guess if you don’t have to phonetically spell it out you have some more freedom in picking what written characters will represent the meanings of the two words. It is still a shame we ended up with those homophones, but I guess that’s just a path dependency thing since the spoken words came first. I guess they just had to work with what they had when they converted them into characters.
