Would you check the sentences and my explanation for them? Is the explanation plausible?

1. "will" indicates future tense; he will die -- no alternative. If you want possibility or guessing, then use "would," "could,"or "might."

2. Correct

3. Correct.

The sentences and explanations you provided are not entirely correct. Let me break it down for you:

1. "He will die." - This sentence is in the simple future tense, indicating a future event that is likely or certain to happen. The use of "will" suggests a natural result or prediction based on the circumstances.

2. "He shall die." - While "shall" can be used to express volition or intention of the speaker, in this particular sentence, it expresses the same meaning as sentence 1. So, it does not necessarily mean that the speaker is going to kill him. It simply states that the person will die in the future.

3. "He will die." (with a different pronunciation) - This sentence indicates the volition or intention of the subject. It implies that "he" intends or wants to die willingly. However, keep in mind that this interpretation heavily depends on the context. In most cases, when people say "he will die" with a different pronunciation, it still means the same as sentence 1.

Overall, your explanations for sentences 1 and 2 are accurate, but the explanation for sentence 3 might not always be applicable. Understanding the meaning of a sentence also requires considering the broader context in which it is used.
