How similar are Spanish and Portuguese?

Alright Spanish and Portuguese speakers, I've got a question for you.

I'm quite fluent in Latin, so I can understand a good deal of both languages, and I find them to be quite easy for me to pick up. I do eventually want to learn both, but I'm wondering how much of a task it'll be. Let's say I learn Spanish first, will I be able to very quickly learn Portuguese? Or will learning Portuguese still take about the same time as it took me to learn Spanish?

I'm not sure if it matters or not, but I'd want to learn European Portuguese. I'm not sure which Spanish dialect I'd want to learn. Probably American Spanish. As far as I can tell, the differences between the European and American Spanish are much smaller than the differences between European and Brazilian Portuguese.

Let me know what you think!

공부하기 가금 재미없어요 저는 한극 사람이 같이 정말 말하고 싶은데, 아직 좀 빡에 못 해요. 그러면, 공부하기만 매일 해야 돼요. 근데, 요즌은, 갈 수록, 더 재미없어요. 그리고, 어떻게 좋아져서 잘 모르겠어요. 아직 한국어 사를 좀 빡에 몰라서, 신사 배 우 해야 돼요. 동사를 정말 배 우 해야 돼요. 근데, 신 동사를 연습하다 써기는 잘 모르겠어요. 그럼, 그냥 더 공부할 거 에요..

Asking someone what they're trying to say If you wanted to ask someone "Do you mean ____?" or "Are you saying ____?" in Korean, would I say: _____라고 무슨 말이예요? 그런데, this is meant as actually asking someone to clarify what they mean. I'm not surprised when asking this. It's more where someone says something to me and I don't fully understand it.

Are both of these ways to say the same thing? Let's say your boss is talking to you about your work schedule, and he tells you "You don't have to work tomorrow." Are there two possible ways to say this? 1. 내일은 안 일 해야 돼요. 2. 내일은 안 일 해도 돼요. Are there slight differences in the nuance of the meaning of these two sentences? Or is one of the above sentences just wrong and isn't said at all?

How do you say "How do you say ____?" in Korean? How do I ask how to say something in Korean?

한국어로 문장을 문제 있어요. How do you say "I don't know what to do today." or "Because I finished all my work, I don't know what to do now." 이 문장 좀 어렵은 같아요. 1. 오늘은 하는 것이 몰라요. 2. 일을 벌써 다 끝나서, 지금 뭐가 해야 되는 것이 몰라요. Are either of my two guesses correct? 감사합니다!

Are these two sentences the same? 지금 듣는 거는 노래예요. = What I'm listening to now is a song. vs. 지금 노래를 듣어요. = I'm listening to a song right now. I'm not sure if the second sentence is even correct, I'm just taking a guess that you can say the same thing these two different ways. Am I right?
