Swedish is an interesting language. On one hand it's easier than English because all of the verbs have a single conjugation, no 'am,' 'are,' or 'is', just a single conjugation for all persons. Also, the present tense covers the continuous tense, so there is no 'ing' form of a verb. This should make the language simpler than English BUT it's still a Germanic language which means it's still prone to the whimsical rules and exceptions that English is. There are two genders, common and neuter. Sort of like the masculine and feminine in Romance languages, but while they have identifiers in the words to tell which is which, Swedish does not, you have to remember what goes to what on a case by case basis.

So far, the most challenging part of the language is the pronounciation. There are 9 vowels in Swedish and they're sometimes too subtle to tell the difference between them. Ö is a tricky one, somewhere between an O and a U but with your lips protruded out more and your tongue where it would be to pronounce the letter E. J and sometimes G are pronounced like a Y, 'Sj' is pronounced like you were blowing out a candle (does that make it a vowel?).
The trickiest thing though is the tones. Like Chinese (thankfully not as bad) Swedish is a tonal language and there are plenty of opportunities for a foreigner to make an ass of himself. 'Anden' depending on the tone, can either be "the duck" or "the spirit/ghost". There are more embarrassing ones out there, I can feel it. I just hope I find them before I say one in front of a crowd of people...
