You are making one huge mistake, Abax, that is not at all uncommon for men (humans) to make.
The Bible was not written by fallible men, struggling to find the best words to convey their message, to those who lived among them at the time of their writing.
The Bible was written by Almighty God through those He chose based on their complete mental, spiritual and physical dedication to HIM and HIS cause. God wrote the Bible TO those who would come much later to inform His beloved of things that were critical for them to understand about history and all things to come. And God is not bound by time or language barriers. If God chose the word world, even in another language, by God, He meant world.
Your complex explanation of the issues with language, from the perspective of men living at that time, are admirable, but woefully inaccurate.
Until you, and those who constantly strive to explain away the Truth and accuracy of scripture, understand these Facts, you will never get a firm grasp on God or His Ways.
You are wrong and Preterism is a lie.
I am fully aware of the Holy Spirit being a true author of Scripture. Now show me His interpretation. I agree He meant world, the word has at least seven definitions. Show me which one He meant.
Maybe the Holy Spirit meant the 10th MW definition?: "the sphere or scene of one's life and action" as in "you're in your own world"?
Maybe the Holy Spirit meant the 14th?: "a celestial body (such as a planet)." I love sci-fi! Maybe He meant the Martian world considering this, the Gospel hasn't been preached there yet!
Maybe the Holy Spirit meant the 13th? Such as "animal world." Maybe the Gospel needs to get to the deep sea to be completed. There are many parts of the ocean we have not explored.
I love the truth and accuracy of Scripture, I love inspiration, inerrancy, and infallibility of the Holy Spirit in Scripture, God, the truest of authors. May He be praised! Now show me what He meant. He did mean world. World means world, amen. World means world, world means world. Which definition?
