Frequently Asked Questions
Does 'extensión' mean an extension cord?
Yes, especially in Latin America. In Spain, they often say 'alargador', but everyone will understand 'extensión'.
Why does the accent disappear in 'extensiones'?
In Spanish, the accent is there to show you which syllable to stress. When we add '-es', the natural stress of the word moves, so the written mark is no longer needed to follow the rules.
Can I use 'extensión' for a deadline extension?
Yes, although 'prórroga' is more formal for deadlines, 'extensión de plazo' is very common and perfectly correct.
