Here's how it works:
* Noun: When used as a noun, "destiny" refers to a predetermined course of events, a person's fate, or a person's ultimate purpose.
* Example: "He believed in his own destiny to become a great artist."
* Adjective: When used as an adjective, "destiny" describes something that is predetermined, inevitable, or fateful.
* Example: "They faced their destiny with courage."
The specific part of speech depends on how the word is used in a sentence.
