a. First Conclusion

20. As to this article, then, let this conclusion be the first that, by extending the term ‘generation’ to cover all introduction of substantial form after privation into matter, there is some generation in the case of nutrition, because (as was argued [n.18]) the matter of the food does not remain under the form of food, nor under any other form than under that of the thing nourished, and it receives that form after nutrition;     therefore etc     .

21. The exposition of this conclusion is that the generation is not called generation simply, because it is not generation of a per se being insofar as what is not part of something else is said to be per se. But it can be called ‘generation-at’, because it is generation of something that becomes, by generation, the same as something pre-existent at which it is generated; or it can be called ‘generation-in’, because it is generation of a part in a whole of which it was not part.
