Articles

When talking about nouns, we use articles:

Questions

To ask a question, you can switch the subject and verb or just change your tone of voice.
Example:

Adjectives

Remember that adjectives must match nouns in gender and number.
Example:

• Un libro interesante (An interesting book - masculine)
