When an incurrence of debt occurs, we say that someone incurs it. Similarly, English demands that for a recurrence relation (the source of recursion schemes and basis of the term "recursion"), we recur. "Recurse" is a backronym adopted by people who were ignorant about english, math, or possibly both. And now it's become a part of literal coder camp names.

Ohh thanks for explaining this. I totally missed this was a grammatical correction. I’m not a native speaker, and I actually learned something from it.

So how should I say “this code is recursing” instead? “This code is ..” ? Or is it solely about the form of “This code recurses”, which should instead be “This code recurs” ? Which also sounds somewhat wrong, because wouldn’t that refer to “recurring” instead of “recursing” ?

Thanks for your explanation, and of course the grandparent as well.

"This code recurs" or "this code is recursive".

"This code is recurring" is correct, but not so idiomatic.

But English is a living language, grammarians should be descriptive not prescriptive etc... "Recurse" (and "Recursing") is a perfectly good backformation, especially because it performs a useful function in distinguishing between two uses of the overloaded verb "to recur".
