Pronunciation of a polish word?

Well this question was asked already but I want to restate it because I just cannot perceive the sound one has to make when it is pronounced:

świat

now what is the sound you hear between the sh and the -ont as in ontology?

is that a v, an f, an h or even a k? What I hear sounds like a very quickly pronounced k, or a hard(what's the adjective for this) h.

I am not studying Polish(though I'd love to learn many languages if I had the chance and Polish is one of them) or something but I love Myslovitz's "Długość dźwięku samotności" (Sound of Solitude), I am trying to sing along, but gee Polish is so hard =))

Thank you.
Wow that was really quick. Thank you very much Alex, I practically racked my brain over it, finding its audio pronunciation and then playing it like a hundred times and sticking my ear to the speakers =D
Oh by the way it's via your answer that I now get to see "świat " and "Świąt!" both are words in Polish - that is unless they were wrongly spelled in the sites I found them.

So there's no n sound in the former but the latter has one right before the t because ą has an "n" sound attached to it as opposed to standard a.

Thanks again =)

Can someone help me write something in polish?

I can speak very well but i can't write that good. I want to say: Hello Grandma how are you I miss you and I hope you are doing well. I think about you everyday and I want to tell you that I love you and I miss you. I got you a mother's day card because you took care of me like I was your daughter and I want to thank you for that. I wish I can go see you in poland. It has been a long time since we seen each other and we used to see each other every year. I think of you daily and I want to let you know i'm doing great. My son will be 4 on May. 22 Me and his father are doing very well we love each other very much and help each other and we are strong together. I want to start school soon when alex goes to preschool in September. Either for the police department or in nursing. i don't know yet it's hard to decide because i don't want to regret what I choose to study. Stephanie is doing good. She is doing very well in school and she misses you too. I will talk to you soon. Love you very much and take care!
