What is the reason behind some words not having some prepositions and are assumed?
For example:
I am home
is a perfectly valid sentence meaning, one has reached home, but if someone completely noob to English come across this sentence, they will probably think:
"I am home", how can a person be a home?
Also, see these sentences:
I go home
Please come here
Go there and purchase your tickets
As you can see, some words like here, there, home don't accept "to" before them.
I go to home
is wrong I suppose.
