Are the sentences grammatical?
Do we have to stress 'will' if we want to express the volition of the subject? If we do not stress 'will', what is the difference?
With the stress on that word, yes, you're expressing the subject's volition.
Without extra stress on that word, you're simply stating something that will happen in the future.
In a written sentence, we cannot know whether it means the volition of the subject or not. In that case how can we distinguish the differene? By context?
Yes, when you're reading, only context will indicate those kinds of things.
Yes, both sentences are grammatical.
In English, the modal verb "will" can be used to express the future tense, but it can also indicate volition or determination when stressed.
In both sentences, "will" is used to express the volition of the subject. However, whether or not you stress the word "will" can affect the emphasis and meaning of the sentence.
1. "You will have your own way."
If you stress the word "will" (pronounced as [wíl]), it emphasizes that it is the speaker's belief or expectation that the person being addressed will definitely have their own way. This usage implies a certain level of determination or certainty on the part of the speaker.
2. "He will have his own way."
Similarly, if you stress the word "will" (pronounced as [wíl]) in this sentence, it implies a strong belief or expectation that the person referred to as "he" will definitely have his own way. It suggests that the speaker believes the person to be quite determined or resolute in achieving their desired outcome.
On the other hand, if you do not stress the word "will" (pronounced as [wɪl]), the meaning of the sentence remains the same, but the emphasis shifts away from the speaker's belief or expectation. It becomes a more neutral statement about the future, indicating that it is likely or expected that the person will have their own way without suggesting any specific level of determination or certainty.
So, the difference lies in the emphasis and the level of certainty or determination conveyed by stressing or not stressing the word "will" in these sentences.
