It's fine.

sie uses a small letter "s" because it means she. When Sie contains a capital "S" it is the proper you, not she.

Hope this helped!

For the same reason that the English sentence uses "she is" and not "she are" -- you have to use the verb form that matches the subject.

bist is only used where the subject is du (you -- when speaking to one person whom you know well).

In the second part of the sentence, the subject is sie (she), and that needs the verb form ist.

• ich bin
• du bist
• er ist, sie ist, es ist
• wir sind
• ihr seid
• sie sind; Sie sind

• ist "is"
• es "it"
• er "he"

In German, the article you use it determined by the gender and case of the noun the article is being used for. "Frau" is a feminine noun, and it is in the nominative case so the article "eine" is used. "ein" is never used with feminine nouns.

Here's an article where you can find all the articles and when they're used: http://en.wikipedia.org/wiki/German_articles

Because German has kept the three genders (masculine, feminine, neuter) of nouns and English has lost them.

So in German, many words (including the definite and indefinite articles as well as adjectives) will take different endings depending on the gender of the noun that they accompany.

When a noun is the subject (in the nominative case), ein is used before masculine and neuter nouns and eine before feminine nouns.

When a noun is the direct object of a verb (in the accusative case), ein is used before neuter nouns and eine before feminine nouns; masculine nouns take einen in the accusative case.

So you can't translate English words such as "a" or "the" 1:1 into German because the German words are sensitive to the gender of the noun while the English ones are not.

ein goes before nouns that are grammatically masculine or neuter, eine before nouns that are grammatically feminine.

The grammatical gender of a noun is something you have to learn; it’s usually not connected to anything related to the thing described by the noun. For example, Mädchen “girl” and Pferd “horse” are neuter and Rock “skirt” is masculine.

Sie ist eine Frau. = She is a woman.

Sie sind eine Frau. = You are a woman.

It does matter. There are rules in German that say that all nouns have to be capitalized. Not doing that is an orthographical error.
