Hi

Hello! How can I help you today?
assistant
I'm trying to improve my vocabulary. Can you give me a word and its definition?
user
The word is "perspicacious," which means having a keen understanding and insight; able to notice and understand things that are not immediately apparent.

That's a great word. How can I use it in a sentence?

Here's an example sentence: "She was a perspicacious observer of human behavior and was able to pick up on subtle cues that others might miss."
