Eldritch Knight's restriction of schools at 3rd level

Question

My GM and I have a minor argument about the wording of the paragraph regarding the Spells Known for Eldritch Knights:

Spells Known of 1st-Level and Higher. You know three 1st-level wizard spells of your choice, two of which you must choose from the abjuration and evocation spells on the wizard spell list.

It says "abjuration and evocation". This suggests to me, that the two school-restricted spells could be both abjuration spells, both evocation spells or one spell from each school.

My GM believes that one spells has to be abjuration, the other one evocation. According to his interpretation I cannot choose both spells from the same list. If that were the case, the wording would have to be "abjuration and/or evocation".

Neither of us is a native English speaker, so we're not sure how to interpret this.

Answer 1

As purely a matter of reading this as a native speaker, the restrictions is that both spells must be chosen from a set which includes all of the abjuration and evocation spells from the wizard spell list.

There is no restriction saying that one must be from each school. If that were the intention, it would probably say something like:

You know three 1st-level wizard spells of your choice, one of which you must choose from the abjuration spells on the wizard spell list and one of which you must choose from the evocation spells on the wizard spell list.

Or, more likely, a different wording entirely. D&D 5E is meant to be written in natural language, not technical code with keywords and mathematical logic. So they might have written something like:

Choose three spells from the wizard spell list. One of these must be from the abjuration spells, one must be from the evocation spells, and the third can be of any school.

But they didn't.

From a language point of view, the "and" in the actual wording serves to create a combined set of both lists. This is a very natural way to say this in English — like "Choose a pet from all of the cats and dogs we have available." That's why it doesn't need to say "and/or" to have the meaning it does. In fact, "Choose a pet from all of the cats or dogs" sounds like you don't know what kind of animals you actually have.

So, because it says you choose from the combined set, you're free to select one of each or two from either.
