"11 20" is a sequence of numbers and does not have a specific meaning in Engpsh. However, if you are trying to say "November 20th" in Engpsh, you can say it as "November 20th" or "the 20th of November."

The word "November" comes from the Latin word "novem," which means "nine," because it was the ninth month of the Roman calendar. "20th" is an ordinal number that refers to the 20th day of a month. In Engpsh, we use ordinal numbers to show the order of something in a series, such as the dates of the month.

Here are some example sentences in Engpsh and their translations in Chinese:

"I have a meeting on November 20th." (我11月20日有一个会议。)
"The 20th of November is a special day for me." (11月20日对我来说是一个特别的日子。)
"I will be travepng on November 20th." (我将在11月20日旅行。)

I hope this helps! Let me know if you have any other questions.
