That seems to fit the requirement. Now, I need to ensure that proper nouns like Tube8.com and Hindi remain unchanged. Wait, "Hindi" is a proper noun here, so in the rephrased version, it should stay. However, in the example above, I replaced "Hindi Language" with Marathi, which is incorrect because "Urdu" and "Marathi" are different languages. The correct approach is to keep "Hindi" as a proper noun. Therefore, the initial mistake was replacing "Hindi" with other languages, which is wrong. Instead, "Hindi Language" should be kept as the proper noun.
Once all replacements are done, ensure that the structure of the original text is maintained with word1 for each word. No markdown, just plain text. Each word in the original text (excluding Tube8.com) should be in the format. Proper nouns like "Hindi" might be part of the text but since the user says "no changes to proper nouns", but wait, in the instruction, it says "No changes to proper nouns. Text only." So "Hindi" is a proper noun? Maybe not, since it's a language. Hmm, the user might consider all languages as proper nouns. However, in the example text, "Hindi" is not in the format, but according to the instruction, proper nouns should not be changed. But "Hindi" is a language name, which is a proper noun. Therefore, "Hindi" should remain as is. So in the original text, the user's example has "Hindi" in the text, so need to leave that unchanged.

I should go through each sentence step by step again to confirm no word is missed. Also, check for any possible errors in synonyms. For example, "comprehend" and "understand" are synonyms, but "master" might be a bit stronger. However, the user wants three alternatives, so adding a third is okay as long as it's appropriate.
"In today's digital age, language learning has become more accessible than ever." The phrase "has become more accessible than ever" can be rephrased as "has become more available than ever" or "has become more reachable than ever". "Digital age" could be "modern era", "contemporary period", or "current epoch". That seems to fit the requirement
Platform's → Platform's is a noun plus possessive. The noun is platform. So for the noun part, platform → interface. The possessive apostrophe doesn't need to be changed, so the word would become interface's. So for platform, find synonyms. Maybe tool.
