What language do most of our pronouns come from?

It's tricky to pinpoint a single "source language" for most of our pronouns. The reason is that pronouns are among the most basic and fundamental parts of language, and they've been evolving alongside languages for thousands of years.

Here's a breakdown:

* Proto-Indo-European: This ancient language is the ancestor of many European and Indian languages, including English. Many pronouns in English have roots in Proto-Indo-European. For example, "I" and "me" come from the Proto-Indo-European roots *eg- and *me-, respectively.

* Old English: English pronouns have been evolving since the arrival of Germanic tribes in Britain around the 5th century. Old English had pronouns like "ic" (I), "þu" (thou), and "he" (he).

* Other Influences: English, as a constantly evolving language, has also borrowed words and grammatical structures from other languages, like Latin, French, and Norse. These influences have impacted pronoun usage and development over time.

In summary: While many English pronouns trace back to Proto-Indo-European, the story of their development is complex and involves a blend of influences from various sources.
