The Anglo-Saxon root "fod" in the word "fodder" is best defined as "food" or "nourishment".

Here's why:

* Etymology: "Fodder" originates from the Old English word "fōdor," which itself comes from the Proto-Germanic word "*fodr," meaning "food."

* Meaning: Fodder is specifically food for livestock, so it reflects the core meaning of the root "fod" - providing sustenance.

Therefore, "fod" in "fodder" denotes the essential concept of "food" or "nourishment" specifically aimed at animals.
