@ChristyJames121410 Well- I must tell you that's quite an interesting request that I wouldn't ever imagine someone would ever ask me about (:D (btw It's nice that you picked up on Spanish! I must say that I myself picked it up as a challenge to learn only three months ago and well~ I do have some difficulties but still I manage pretty well! ^_^) Okay, okay but- Back to your question! I must say I don't see myself in the role of a teacher but I would be more than happy to help you learn our *weird* language we've got in my country ;) SO let's say I could help you out if you would ever have some difficulties in it, but first I would recommend you learn the basics first things first - like our ways to say goodbye and hello!
Good Morning! - "Dzień dobry" or 'dobry (this is more of a short saying if you are in a hurry) or you could say: 'bry! (which is even a shorter saying if you are in a really BIG HURRY) ((And yes while I know they don't teach that anywhere, trust me when you've been in Poland for a long time, you eventually start hearing people say these kind of words))
now for the more casual ways you can say:
Hey! - Hej
Hello! - Cześć
'sup - Siema
now for greeting in the afternoon and the evening, there is only one fortunately even though it is more of a polite word than a casual one because you don't hear it often nowadays- :
Dobry wieczór! - Good evening/afternoon
and for our way to say good night, we say:
Dobra noc! - Good night
Now I think there is probably far more words to cover for the basics but if you really want to learn Polish like a PRO! ;P I recommend that you search for some Polish learning vids on YT or you could even try to learn it up on Duolingo.
(Best tip also- I really recommend first learning the alphabet before trying to say any Polish words since there may be some confusion when it comes to pronunciation on most of them .-.) and if you have any more questions, please go ahead I'm all ears :>
