gravitas

Gravitas is seriousness and dignity. You might try to speak with gravitas, but no one will take you seriously if you're wearing clown makeup and giant floppy shoes.

Gravitas is a Latin word that means "weight or heaviness." It came to mean a figurative weight after gravity acquired a primarily scientific meaning. A biography of Abraham Lincoln will inevitably be full of gravitas, and places like libraries, museums, and university buildings seem to have gravitas, or dignity — while grocery stores and gyms usually do not.
