Here is how to say "800 words or more" in English:
Eight hundred words or more
Eight hundred words minimum
At least 800 words
No less than 800 words
800 words or greater
800 words or above
800 words or beyond
800 words and up
800 words and above
800 words and beyond
The most common and direct way to express this requirement would be:
"The essay/paper/document should be 800 words or more."
This clearly conveys the minimum length requirement of 800 words. Other variations like "at least 800 words" or "no less than 800 words" work as well and provide the same meaning.
The key is to use a phrase that sets the lower bound at 800 words, indicating that the text should be 800 or more words in length. This gives the writer the flexibility to exceed the minimum as needed to fully address the topic or requirement.
