The verb with prepositions sometimes gives me a trouble to understand.
What does "out" mean in those sentences?
Is there any difference if there is no "out"?
We moved out here and don't ever plan to move away.
When we came out here, we were just visiting friends.
The 'out' indicates a distance from a 'there' which is some understood center-- as for instance the downtown area of a city, or the more-populated area of a state or country. 'Here' alone would not express that quality of 'there'.
It means 'outside' in some sense, and is therefore similar to its use in 'We went out for some fresh air'.
