* Verb: "I attribute my success to hard work." (Meaning: to consider something to be the cause of something else)
* Noun: "One attribute of a good leader is confidence." (Meaning: a quality or characteristic)
* Adjective: This usage is less common but possible. "The attribute value is missing." (Meaning: relating to an attribute, especially in a database or software context)
So, without context, it's impossible to say definitively which part of speech it is. You need to look at the sentence it's used in to determine its function.
