According to Oxford Learner's Dictionary,

> 
> [**next to**](http://www.oxfordlearnersdictionaries.com/definition/english/next-to?q=NEXT%20TO)
> 
> 
> 1. in or into a position right beside somebody/something
> 2. following in order or importance after somebody/something
> 
> 
> 

If:

> 
> A is **next to** B
> 
> 
> 

it should mean that A is immediately beside B (as per the cited definition). I would normally assume that A comes after B or is to to B's right.

**Context**
-----------

I'm trying to the solve the "Einstein's Riddle" and two of the givens are:

> 
> * The Norwegian lives in the first house.
> * The Norwegian lives next to the blue house.
> 
> 
> 

If the Norwegian is the first house in a row of five houses, it can't possibly come after the blue house. In this case, knowing the correct position is most important. What should I assume? I'm arranging the houses *horizontally* from left to right. So, will the N house be leftmost? If so, will the blue house be to its right?

Question
--------

Now the question is:

> 
> Is A to the right of B? Or to the left?
> 
> 
> 

Definition #2 seems to suggest that A comes *after* B — that is, to the right (assuming things are ordered from left to right, as is generally). 

However, if A and B are next to each other, A is to the right of B, and B is to the left of A. Either ways are possible then.

Which one is a correct interpretation of '*next to*'?
