This word is the kanji same with hiragana attached. Since the hiragana doesn't suggest it's a verb or adjective, you can assume it's a noun. What's the noun version of "same"? It's also same.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you:
When you think of the word "same" think same owner (おな). You're looking at a restaurant that has a sign that says, "New owners!" However, when you walk in you see it's the same terrible owner you remember from before. What a liar.
