Writing Brush
Paintbrush, Brush
noun
The kanji and the word are exactly the same. That means they share meanings as well.
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 to remember: For as long as you can remember, your family and another family has had a bloody feud (ふで) over this one writing brush. Just think of all the people killed over this brush. This feud has to end.
