multisite

Hi,

My multisite is on http://nepalese.co/ so my first blog is itself http://nepalese.co/

And when I post a post, the web address of my post become:

http://nepalese.co/blog/rara-lake/

the world "blog" automatically comes in post of my first blog. how can I change this term "blog" to "news" or, "update".

Looking forwards for your help.

Thank you very much,
Jay
