help with phrase of head
Hi everyone,
why do 'head up' and 'head down' mean 'go north' and 'go south'. Is there any difference between these 'head' phrase and 'go' phrase? Additionally, head over means go over , head inside means go inside, and head back means go back. Which ones are more common in your daily life?
And how do you use 'head off' and 'head for'?
Thanks
