So, for each term in the text except proper nouns, replace with 3 synonyms. Let's go through the user's latest input:
- "uploaded" might be replaced with "transferred|submitted|uploaded".
Let's start reconstructing the text with replacements:
Wait, the user's instruction says "every word with 3 variants". Wait, does that mean every word in the entire text? But proper nouns shouldn't be changed. So, for example, "Knjiga" is a proper noun? Or is it part of the title "Knjiga O Milutinu"? The user says "No changes to proper nouns." So I need to leave any proper nouns as they are.
"Ensure": ensure.
I need to ensure that the substitutions maintain the original meaning. For example, in step 3, "format" as "structure" might not be correct. Maybe "format" should be "type|format|specification"? Wait, the user said "set to PDF" so "format" is about the file type. So maybe "type" is better than "structure".
