Matching Gender and Number
Since this is a describing word, you must change the ending to match what you are talking about: 'un libro anticuado' (masculine) but 'una idea anticuada' (feminine).
Using Ser vs. Estar
Use 'ser' if being old-fashioned is a permanent trait (like a 1920s house). Use 'estar' if something has simply become out of date over time compared to something else.
Confusing 'Viejo' and 'Anticuado'
Mistake: “Ese teléfono es viejo.”
Correction: Use 'anticuado' if you mean the technology is behind the times. 'Viejo' just means it has existed for a long time.
