What's the difference between the "wave" and "tsunami"?

Native speaker’s answer

Rebecca

The difference between a "wave" and a "tsunami" is actually very technical and has a lot of scientific qualification. However the basic difference is that "tsunamis" move through the entire water column, the full depth of the ocean. This means they affect all the way from the ocean surface to the ocean floor. However "waves" generally only affect the near-surface layer of the ocean. It doesn't reach to the bottom of the ocean the way a "tsunami" does.

Should we use "to" when recommending something? So should this sentence be "Do you recommend people TO eat Durian"?
No, the word "to" isn't really necessary when recommending something. You can add "to" in the sentence, but it's not always needed. It really just depends on the structure of the sentence. Here are some examples of recommending others to something with and without the word "to." Ex: I recommend that you eat pineapple. Ex: It is recommended that you go to college for certain careers. Ex: Do you recommend that others try eating more vegetables?

What's the difference between "start", "begin" and "commence"? For example, I've often seen the antagonist of the movies saying "commence the attack" instead of saying "start the attack", however it's hard to tell the difference.
In this context, they pretty much mean the same thing! What's different here is the tone. "Commence" has more of an official tone than "start". I'd also say "start" has a few more meanings than the other two words. "Commence" and "begin", both mean for an event or something to begin. "Start" does have the same meaning as begin in some contexts! However, it also means for something to happen or exist, the beginning of something, or a sudden movement. Ex: Jill tried one more time to start the fire, and it worked. Ex: The race is going to begin at five am. Ex: Let me tell you a story, It all started when I was ten years old, and I baked my first cake. Ex: Commence lift-off in: Three. Two. One. Lift-off!

Isn’t this sentence necessary "the" before "easy way"?
If you're regarding listening, I'm afraid there is no 'the' before 'easy way'. Regarding grammatically, only using 'the' before easy way is grammatically correct, but phrases like 'what the easy way' feels very awkward. Using 'What easy way' or 'What is the easy way' would be more natural.

What does “be about to” mean?
