Here's how to tell which one it is:
Verb:
* Example: "She made a delicious cake." (past tense of "make")
Past Participle:
* Example: "That is a made-to-order cake." (adjective modifying "cake")
* Example: "The cake had been made hours ago." (part of the verb phrase "had been made")
So, the meaning of "made" depends on the context of the sentence!
