What is the translation for this

So I don't know Japanese but when I use google translate I notice that somethings are reversed for example,

world of today translated to 今日の世界

but isn't 世界 world, so why is it last?

So what would the correct translation be?

Because it's Japanese, not English... The particle の shows ownership. So it's essentially "today's world", I.e. the world of today.

Grammatical structure of a sentence (or phrase) is very different between English and Japanese.
of in English is preposition (meaning it comes before the noun), while の comes after a noun.

今日の = of today
世界 = World

It's more like saying "Today's world" in English.

The meaning of の is much more general than "ownership". Basically, AのB, where A and B are nouns, means that A describes or modifies B in some way. It can be that B belongs to A, such as in 先生の車, but it can be something else. Consider for example 日本人の女子, or 数学の教科書, or 友達の春香さん, or...

Of course, but it that context it is. I thought it best not to confuse the OP, who does not know Japanese.

If you say flat out that "の = ownership", then OP will perhaps not be confused now, but he will certainly be confused later when he encounters a の where the "ownership" interpretation makes no sense (arguably, it makes no sense here either).

Personally, I like to think people are intelligent and able to understand things, at least until proven otherwise.

AのB.
the main subject is "B". "Aの" is "adjective". "の" can change the noun("A") to adjective.

Ahhh ok this makes much more sense. Thank you all!
