You know it's a definition because it provides the meaning of the word inside commas directly after the word. It's not a synonym nor an antonym because it's not one word, and it's not an inference because you're not making an educated guess about the word based on the rest of the sentence. The sentence is <em>directly</em> telling you what the unknown word means, so it must be a definition.
