Advance vs. AdvancedHow to use "advance" and "advanced" correctly
Some people are under the impression that only the word advanced (the past participle form of the verb to advance) can be used as an adjective. In fact, the word advance itself can be an adjective when it refers to something ahead of time, though it is generally only used before a noun:
Their technology was advanced.
advance party sent to secure the area
The notice was advance.
