The word "exocoelic" is derived from the combination of two root words: "exo" and "coelic".
1. "Exo-" is a prefix derived from the Greek word "exo", meaning "outer" or "outside". It is commonly used in English to indicate something external, as opposed to internal. For example, "exoskeleton" refers to the hard external covering of an animal.
2. "Coelic" is derived from the Latin word "coelicus", meaning "belonging to the heavens" or "celestial". It is related to the Latin word "caelum", meaning "sky" or "heaven".
Therefore, the word "exocoelic" combines the prefix "exo-" indicating something external or on the outside, with "coelic" meaning celestial or belonging to the heavens.
