Let’s talk about plural nouns. Also, functions that return other functions, advanced regular expressions, iterators, and generators. But first, let’s talk about how to make plural nouns. (If you haven’t read the chapter on regular expressions, now would be a good time. This chapter assumes you understand the basics of regular expressions, and quickly descends into more advanced uses.) -
English is a schizophrenic language that borrows from a lot of other languages, and the rules for making singular nouns into plural nouns are varied and complex. There are rules, and then there are exceptions to those rules, and then there are exceptions to the exceptions. - +
English is a schizophrenic language that borrows words from many other languages. The most basic linguistic operations, like taking a singular noun and turning it into a plural noun, are complicated by the language's mixed heritage. There are rules, and then there are exceptions to those rules, and then there are exceptions to the exceptions. +

If you grew up in an English-speaking country or learned English in a formal school setting, you’re probably familiar with the basic rules:

-How do you know that the code you wrote yesterday still works after the changes you made today? Every seasoned programmer has war stories of an “innocent” change that couldn't possibly have affected that other “unrelated” module… If this sounds familiar, this chapter is for you.

In this chapter, you're going to write and debug a set of utility functions to convert to and from Roman numerals. You saw the mechanics of constructing and validating Roman numerals in “Case study: roman numerals”. Now step back and consider what it would take to expand that into a two-way utility.

In this chapter, you're going to write and debug a set of utility functions to convert to and from Roman numerals. You saw the mechanics of constructing and validating Roman numerals in “Case study: roman numerals”. Now step back and consider what it would take to expand that into a two-way utility.
The rules for Roman numerals lead to a number of interesting observations:
- There is only one correct way to represent a particular number as Roman numerals.
