Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means bury so the verb vocab version is to bury as well.

埋める can also mean to fill, and can refer to filling a hole, vacancy, or gap. Note that this word can be used to refer to filling in figurative holes and gaps too, like a hole in one’s finances!

You learned this reading with the kanji, how nice for you!

However, you might notice that in addition to うめる, there's another reading too: うずめる. うめる is used for the act of burying something or filling in a hole, while うずめる is used when describing the covering or concealment of something, or when burying one's face in something (like a fluffy cat!)
