The English word "actually" translates to "realmente",or "en realidad", like Perla said. The Spanish word, "actualmente" LOOKS like the English "actually", but it really means "currently". It's called a "false cognate"; a word that *looks* almost the same in another language, but means something completely different.

Actually I don't know how to say that = Realmente no sé cómo decir eso. En realidad no sé cómo decir eso.

"Quiero traducir esta oración". You also can say: quiero traducir esta frase quiero traducir esto quiero traducir lo siguiente Actually I don't know how to say that - Actually means "en realidad". It's a false friend in spanish-english translations: ACTUALLY = en realidad NOWADAYS, CURRENTLY = actualmente So, it would be: "en realidad, no sé cómo decir eso" Any question, don't hesitate to ask me

Actually I don't know how to say that = En realidad no se como decir eso.

"Actualmente no sé como decir eso."
