Inflection

An inflector can be used to convert a noun back and forth from its singular and plural forms. This is useful when generating natural language, as the plural versions of nouns might not be obvious:

let inflector = new natural.NounInflector();

console.log(inflector.pluralize('virus'));
console.log(inflector.singularize('octopi'));

The preceding code will output viri and octopus, respectively.

Inflectors may also be used to transform numbers into their ordinal forms; for example, 1 becomes 1st, 2 becomes 2nd, and so on:

let inflector = natural.CountInflector;

console.log(inflector.nth(25));
console.log(inflector.nth(42));
console.log(inflector.nth(111)); 

This outputs 25th, 42nd, and 111th, respectively.

Here's an example of the inflector used ...
