What is the root meaning of talk or knowledge?

The root meaning of both "talk" and "knowledge" can be traced back to the Proto-Indo-European (PIE) root "*dʰēḱ-", which means "to show, to point out, to teach."

Talk:

* Old English "talu" (speech) derives from the PIE root "*dʰēḱ-*" through Germanic and Proto-Germanic transformations. This connection highlights how "talk" originally meant to "show" or "point out" something through speech.

Knowledge:

* Old English "cūþ" (known) is also linked to the PIE root "*dʰēḱ-*". In this case, it suggests the idea of "being shown" or "being made known."

Summary:

While "talk" and "knowledge" seem like separate concepts, their common root reveals that both originally meant to convey information and understanding. "Talk" is the act of "showing" or "pointing out" information, while "knowledge" refers to "being shown" or "being made aware" of it.
