/**
 * Trait InflectionHyphenizeTrait

trait InflectionHyphenizeTrait
{

    /**
     * @param $word
     * @return string
     */
    protected function doHyphenize($word)
    {
        $word = $this->doUnderscore($word);

It seems like doUnderscore() must be provided by classes using this trait. How about adding it as abstract method to this trait?

        return str_replace('_', '-', $word);
    }
}
