The false friend that trips up nearly every English speaker

Actualmente

ac-twal-MEN-teh — Currently / at present — NOT "actually"

"Actualmente vivo en Madrid."
I currently live in Madrid.

It looks exactly like "actually," but it means "currently." If you want to say "actually" (as in "actually, that's not true"), the word you want is "en realidad." This is one of the most common mix-ups English speakers make.

"This false friend causes more confused faces in my lessons than almost any other word. I love the moment it finally clicks."— Graciela
