Rice Bowl
Donburi Bowl
noun
The kanji and the word are exactly the same. That means they share meanings as well.
To be exact, 丼 refers to a chinaware bowl that's bigger and sturdier than your ordinary rice bowl. It's often used for one-bowl dishes like katsudon, gyūdon, poke, but also noodle soups like ramen!
You learned the どん reading for this kanji, and this reading is just an extension of that, coming out to どんぶり. This change might be a little tricky to remember, so here's a mnemonic to help you out:
Rice bowls keep disappearing, and everyone's terrified. Who's behind it? Don Brie (どんぶり), the feared cheese-loving mafia boss. He wants those rice bowls to eat all his brie out of, because I guess plates aren't good enough. That's why they call him Don Brie.
