It is the root of many English words, such as:
* eloquent: meaning fluent and persuasive in speaking or writing.
* loquacious: meaning tending to talk a great deal; talkative.
* colloquial: meaning characteristic of informal spoken language.
* soliloquy: a speech in which a character speaks their thoughts aloud when alone.
So, when you see "loqui" in a word, you can usually assume it has something to do with the act of speaking.
