I'm not a native English speaker. Sometimes preposition(or adverb) makes me crazy. Look.
He went up to the girl and asked her to dance.
Mr. Jones had to drive up from London to Edinburgh in Scotland.
In these sentences, I don't know what does 'up' mean. I understand what 'up' means in these sentences.
I climbed up to the top of the mountain.
But when we use 'went up to...' What nuance of meaning of the word 'up' is here? So, Because the girl was on the higher place than him, he went 'up' to the girl and asked her to dance?
What is difference between 'He went up to the girl' and 'He went to the girl'. Is it possible to omit 'up'? Would it still be the same meaning? What meaning of the word 'up' has here?
'He had to drive up from London to Edinburgh'. In this sentence I think Edinburgh is located more northern than London on the map, So If Edinburgh(I don't know where Edinburgh is) was located more sothern than London, could I write like this: 'He had to drive down from London to Edinburgh'? Am I right?
