She is alone.
She is lonely.

What`s the difference between two sentences and if you want to teach somebody these two words how can you teach?

Not a teacher.

I would say 'alone' has a physical aspect to it, whereas 'lonely' is a mental state/feeling.

Alone - no one else physically present. A person can be 'alone' but not feel 'lonely'.

Lonely - Feeling like the only one, wishing for company.

Like I said, I'm not a teacher, only a native.
