Hello. I am non-native speaker in English. Even though im doing well, im still wondering if there are syllable combinations that are hard to pronounce even for native speakers? Because i need much practice to improve my pronounciation. Its hard for me, but miscluding that, there seems to be some combinations for me that are hard to pronounce. For example "that the", when rapping in fast flow. I cant seperate those two words and i dont know if it sounds naturally when i try to. Or it should sound like "tha the", without t letter at the end?
