TPH dictionary: finial

As usual, another unknown designer term has been introduced to me. Finial. Now that this is my umpteenth completely new word/definition combo, I'm starting to get used to the fact that I'm in learning & absorption mode. When Audrey used finial when describing something to me the other day, I actually got excited when I started thinking about the process of looking up what it means and then sharing it with you!
***
fin·i·al
noun \ˈfi-nē-əl\
1 :  a usually foliated ornament forming an upper extremity especially in Gothic architecture
2 :  a crowning ornament or detail (as a decorative knob)
***
This is a pretty broad definition, so I found two examples of finials to help us understand this thing better. One is stand alone, and the other serves as a resting place for a candle or some other object. They can also be used as bases in lamps!

I like this new word, and I like what it is! Enjoy!
