The kanji and the word are exactly the same. That means they share meanings as well.

暇 means the spare time or free time you have when you're not busy with work, school, or other obligations. It can also indicate a slow period for a business or a time when you have nothing to do, often suggesting a sense of boredom.

Since this word is made up of a single kanji, it probably uses the kun'yomi reading. You did not learn this reading, so here's a mnemonic to help you remember:

In your spare time you like to drink hima (ひま), an off brand version of Zima.
