I WILL SEE YOU IN A "FORTNIGHT"!
This is a word that very few of my students know. If you use it when you speak English then...I am impressed! Well done. To those of you who are not sure what it means, the basic translation is "dentro de dos semanas".
There are other ways to say this that are a little easier such as: "in two weeks" and many of you will want to just stick to the easy version when you are speaking (that is fine) but you also need to be aware (ser consciente) about what a "fortnight" means because when a native speaker uses it, you want to be able to understand it "a la primera" (instantly / immediately)!
Hope that helps!
