Morphology

homoousion = homo + ousion

Although the combining form 'homo-' means 'same', the core element 'ousion' is a specialized Greek theological borrowing ('essence') not recognizable to an average B1 learner, so the meaning cannot be reliably derived from the parts.

Etymology

Homoousion comes from the Greek parts homo- 'same' and ousia 'being' or 'essence'. So homoousion means that the Father and the Son share the same being or substance, which is why the word was used to say they are of one essence in early Christian debates.
