Singularization

[cristcost]

Would be interesting to have the capability to transform plurals to singular:

System.out.println(English.singular("words")); // == "word"

System.out.println(English.singular("words", 1)); // == "word"
System.out.println(English.singular("words", 2)); // == "words"

👍

+1. My data values are > 1 almost all the time and I occasionally hit singular values

I agree. I downloaded this library because I assumed it would support singularization too. Sadly, I was mistaken. This project has a lot of potential though!

If anyone is interested, I've ported this to Scala and implemented singularization here: https://github.com/hypertino/inflector To use it add dependency:

<dependency>
    <groupId>com.hypertino</groupId>
    <artifactId>inflector_2.11</artifactId>
    <version>1.0.0</version>
</dependency>

And make a call: com.hypertino.inflector.English.singular("cats") - returns 'cat'

I realize this is an old issue, but did anyone ever find a way to accomplish this? I saw the Scala port, but would prefer to keep the libraries I use pure Java. In addition when I tried pumping many values through the Scala port I got exceptions. For example:

System.out.println(English.singular("days"));

produces this exception

Many other words do work so I don't know what is wrong with that.
