How can I find the category parent for a post. Say that I have:
- Category 1a
- Category 2a
If i put a post under Category 1a, how can I find out that the parent category is Category 1? With how the taxonomy system is setup, I don't see a very clear cut way to do this.
Thanks in advance for any help.
