It's the root of many English words, including:
* Loquacious: Talkative
* Eloquence: The ability to speak fluently and persuasively
* Circumlocution: The use of more words than necessary, often to avoid saying something directly
* Soliloquy: A speech given by a character alone on stage, revealing their thoughts and feelings
Therefore, "loquor" is essentially the Latin word for "to speak" and it's used in various ways to describe the act of communication.
