get and go: movement

Go is used to talk about a whole movement.

Get is used when we are thinking mainly about the end of a movement – the arrival. Compare:

• I go to work by car and Lucy goes by train.
  I usually get there first.
• I went to a meeting in Bristol yesterday.
  I got to the meeting at about eight o’clock.

We often use get to suggest that there is some difficulty in arriving.

• It wasn’t easy to get through the crowd.
• I don’t know how we’re going to get over the river.
• Can you tell me how to get to the police station?

For get and go meaning ‘become’, (see here).
