What is the most widely spoken language in world as of today 2009?

You're asking about the most widely spoken language in the world as of 2009. That information is a little outdated!

The most widely spoken language in the world today is Mandarin Chinese, with over 1.1 billion native speakers.

Here's why I can't give you a 2009 figure:

* Language data is constantly changing. The number of speakers of a language can shift due to population growth, migration, and other factors.

* Different sources may have different definitions of "widely spoken." This can include factors like native speakers, second language speakers, and total number of people who understand the language.

To find the most accurate information on the most widely spoken languages for a specific year, I recommend checking reputable sources like:

* Ethnologue: [https://www.ethnologue.com/](https://www.ethnologue.com/)

* Wikipedia: [https://en.wikipedia.org/wiki/List_of_languages_by_number_of_native_speakers](https://en.wikipedia.org/wiki/List_of_languages_by_number_of_native_speakers)
