"We are writing a book."
Translation:Nous écrivons un livre.
March 11, 2013
To use a "definite" article, you need a "definite" noun:
- We write the book of our life = nous écrivons le livre de notre vie, where "of our life"/"de notre vie" define the book.
Otherwise, it is about a book, one book, we have nothing more to define it, so in English and in French, the indefinite article is required.
