AI training is an expensive and computationally intense process that happens rarely, usually prior to the launch of a major new AI model, although a secondary process called "fine-tuning" can continue over time. Having access to high-quality training data, such as vetted journalism, improves AI language models' ability to provide accurate answers to user questions."
The example that I think most native English speakers learn at some point is the reason for the distinction in food words: we eat pork (porc) and beef (boef) but they are the flesh of the pig/swine (Schwein) or cow (Kuh). This reflects the elite's use of French (thus using French words for food on the table) while the English servants used their Germanic vocabulary for the animals they worked with.
In both French and German the same word is used for the animal in the field and on the plate.
And then there are innumerable hybrids (anglicized french words). With regards to food and husbandry, one my of favorites is "beeves" ("cattle" -- "beefs"): while I have never heard the word spoken aloud I have seen it in novels even as late as the early 60s.
