I'm working on the Sententiae Antiquae for Chapter 36 (6th Ed. Revised) and am having trouble with this sentence:
Omnia fient quae fieri aequum est.
Could someone explain the grammatical structure to me? I have a rough idea of what it is trying to convey but am not sure how the grammar works.
What is the function of the infinitive "fieri"? And why does aequum take a singular form?
