Questions & Answers about ¿Estáis enfadados con ella?
Who exactly is being asked this question, and why do we use estáis?
Estáis is the "you all" form of the verb estar. In Spain, this form (called vosotros) is used when you are talking informally to a group of people, like friends or family members. Notice the written accent mark on the á!
Why do we use a form of estar here instead of ser?
Why does enfadados end in -os?
In Spanish, adjectives must match the people they describe in both gender and number. Because estáis refers to a plural "you all" (either a group of males or a mixed-gender group), the adjective enfadado becomes plural and masculine: enfadados. If you were talking to a group of only women, you would ask: ¿Estáis enfadadas?
Why do we say con ella? Doesn't con mean "with"?
Yes, con means "with". In English, we often say we are "angry at" someone, but in Spanish, the expression is always estar enfadado con (literally, "to be angry with"). You will use con whenever you want to say who someone is mad at.
