Who invented the word 我?

The word "我" (wǒ, meaning "I" or "me" in Chinese) wasn't invented by a single person. It's a very old character with a long history that predates written records.

Here's what we know:

* Origins: The character "我" is believed to have evolved from pictographic writing, meaning it was originally a picture representing the concept. Some theories suggest it may have depicted a person with their arms outstretched, representing the self.

* Ancient Usage: The earliest known use of the character dates back to the Shang Dynasty (1600-1046 BC), found on oracle bone inscriptions.

* Evolution: Over centuries, the character's form has changed slightly, but its meaning and pronunciation have remained consistent.

Therefore, it's impossible to pinpoint a specific inventor. The character "我" is a product of collective linguistic evolution over thousands of years.
