Are final stop consonants like 't' and 'k' silent in Thai pronunciation?

I'm very probably out of my depth in this conversation, but I did read that ending consonants are not aspirated, ie, they are just the way air is stopped, which makes them much more subtle than English ending consonants, but still discernable once you learn to hear it. Think you're probably a bit further on this than me though.

Obviously the letters with the "silent mark" over them are silent. But the issue is that there are some words that just have a silent letter with no rule associated with. Similar to any other language. My textbook has rules for 5 different letters that should be silent, but there are also 2 other rules that say as follows:

1) Sometimes consonants can just be silent without a silent mark at all

ปรารถนา has a silent ร

สามารถ has a silent ร

ไทย has a silent ย

พุทธ has a silent ธ

2) You can see some other cases apart from the previous rules about -ติ and -ตุ where the vowel is not pronounced

ภูมิใจ has a silent . ิ

พยาธิ has a silent . ิ

@Josh ********

you can buy a thai-book for primary school students at most book shops, they're inexpensive and if you know how to read Thai you'll find it all explained there (though it's explained in examples and not in "rules"). If you want to know the linguistic rules, a thai dictionary won't do, you'll have to get scientific works of the thai language which you probably will have to get through a university.

This is for the end of a syllable

Forgot the dentals, they're also silent.
