Translation of collateral in German

Probably we will make additions to our dictionary. I'll be available in January and in February, but not in March, because I'll be in the United States for about three months. About a week in New York, a week in Chicago and Detroit.

When I wanted to do my homework, I accidentally landed on Vocabulix and it caught me right from the beginning. Connecting with other users can be brilliant. Skyping with them, chatting and messaging. Great idea.
