Cultural Tip
In many Spanish‑speaking households, people often say *apagar la luz* for a single source and *apagar las luces* for several. Remember that *luz* is feminine, so the article and adjectives must be *la*/*las* and *toda*/*todas*. In some Latin American countries, the pronunciation of the ‘c’ in *luces* is /s/ (luˈses) rather than the Castilian /θ/ (luˈθes).
