Nickname

home of

I'm from Tennessee, the home of Jack Daniel's whiskey and Elvis Presley.

If you are talking about the 'home of' something or someone you are referring to where it was first made or born.  We usually use this phrase only to talk about famous people or products.  Notice the following:

1. Where is the home of jazz music?
   
2. Did you visit the home of Bob Dylan?
   

most obvious

The most obvious reason is that I'm from Tennessee.

If a reason is the 'most obvious' it is the easiest to see or recognize.  Notice the following:

1. That is the most obvious decision ever.
   
2. This is the most obvious solution to the problem.
   

I see

Now, I see why they gave you that name.

We can use the phrase 'I see' to show that we understand why something was done.  Notice the following:

1. I don't think I see where you're coming from.
   
2. I see why she likes him.
   

get confused

Because there were four Davids here, we were getting confused.

If you 'get confused' it means that it is difficult to keep things in order in your head or you don't exactly understand something.  Notice the following:

1. She always gets confused without a GPS.
   
2. Do you get confused when you try to construct things?
   

keep from

So, to keep us all from getting confused, they just called me Tennessee.

If you 'keep someone from doing something' you prevent them from doing this action or activity.  Notice the following:

1. How do you keep from falling asleep in class?
   
2. To keep myself from eating chips I don't buy them.
