Which word means to boast or display pride?

The phrase "show off" effectively captures the meaning of boasting or displaying pride. When someone is showing off, they are actively presenting their achievements, possessions, or qualities in a manner that seeks attention and admiration from others. This aligns precisely with the notion of boasting, where an individual may express bragging rights or highlight their abilities or successes in a way that draws focus.

The other options suggest different actions that do not align with the idea of boasting or showcasing pride. To "hide" means to keep something out of sight, while "conceal" carries a similar meaning of keeping something hidden. "Magnify" refers to making something larger or more significant but does not inherently imply displaying pride or boasting. Hence, "show off" is the most fitting choice as it directly relates to the act of boasting and expressing pride outwardly.
