1. However you may go, I will follow you.

2. No matter how you may go, I will follow you.

3. However you go, I will follow you.
4. No matter how you go, I will follow you.
[Can we use both 'go' and 'may go'? Any difference?]

5. It helps us talk to people at any place where they are.

6. It helps us talk to people wherever they are.

7. It helps us talk to people no matter where they are.
[Can #5 mean either #6 or #7? Or does #5 mean #6 alone?]

Yes, in this case, "go" or "may go" are okay.

However, when speaking of a method (how will you get there?), how and ever are two words, not one. However is a conjunction. "Your thesis is interesting, however, it is wrong." "How ever (with a push mower, a scythe, or a power mower) you cut the grass, it must be cut today."

5, 7, and 7 mean the same. #5 is awkward.

1. Wherever you may go, I will follow you.

2. No matter where you may go, I will follow you.

3. Wherever you go, I will follow you.
4. No matter where you go, I will follow you.

1. "However you may go, I will follow you" and "No matter how you may go, I will follow you" are both correct sentences. These sentences emphasize the fact that the speaker is committed to following the other person, regardless of the path they choose. The use of "may go" adds a sense of possibility or choice.

2. "However you go, I will follow you" and "No matter how you go, I will follow you" are also correct sentences. These sentences express the same idea as the previous two examples but use the simple present tense ("go") instead of the modal verb "may." The meaning remains the same; the speaker is committed to following the other person, regardless of the method they choose.

3. "It helps us talk to people at any place where they are" means that the speaker's ability to connect with people is not limited by location. They can talk to people wherever those people happen to be.

4. "It helps us talk to people wherever they are" is similar to the previous sentence but uses the word "wherever" to emphasize the flexibility of the communication. The speaker can communicate with people regardless of their specific location.

5. "It helps us talk to people no matter where they are" means the same thing as the previous sentences. The word "no matter" indicates that the speaker's ability to talk to people is not affected by the location of those people.

In summary, sentences #5, #6, and #7 all express the same idea; the speaker can communicate with people regardless of their location. Although there are slight differences in wording and emphasis, the meaning remains unchanged.
