The chain of being is composed of a great number of hierarchical links, from the most basic and foundational elements up through the very highest perfection, in other words, God. God sits at the top of the chain, and beneath him sit the angels, both existing wholly in spirit form. Hope that helps.
The great chain of being is a strict, religious hierarchical structure of all matter and life, believed to have been decreed by God. The chain starts from God and progresses downward to angels, demons (fallen/renegade angels), stars, moon, kings, princes, nobles, commoners, wild animals, domesticated animals, trees, other plants, precious stones, precious metals, and other minerals.
'Well spoke' means that you said it in an excellent way. It means that you used great vocabulary and how you structured the sentence was amazing. Keep up the great work, since a professor complemented you! xD
