Morphology

de + novo

The sense ‘arising newly’ is directly compositional from Latin constituents de (of/from) + novo (new), so a learner who knows those morphemes can derive the meaning as ‘anew’ or ‘newly arisen’. This construction also parallels forms in Romance languages and scientific register usage, making the semantics transparent for learners familiar with the parts.

Etymology

De novo also comes from the Latin parts de 'from' and novo 'new', so it gives the image of a change that appears 'brand new' in a person. That's why a de novo mutation is one that appears in the child and was not inherited from the parents.
