I did a line by line translation of the Perl code into Python, got that working and am now slowly redesigning the code. I am currently removing many of the regular expressions, which makes the code many times faster (and clearer, I think). The code alternates between applying rules and using lists of words. The author of the original Perl code, Damian Conway, wrote an academic paper on the approach taken. http://www.csse.monash.edu.au/~damian/papers/HTML/Plurals.html A future goal is to have this work in a way that is far more pluggable and so be applicable to other languages. But at the moment I'm happy to have got it working. I'm pretty sure that if Damian was writing this from scratch today he would design it differently. However, I had existing Perl code that worked, so I would rather start with that, get it working in Python and covered by tests. Then I can improve the design with the safety of test coverage. The Perl version is called Lingua::EN::Inflect, so was more explicit about being for English in its naming and there are other Perl Lingua::XX::Inflects for other languages. But my lack of mentioning English in the announcement was an oversight. Both the Perl author and I are Australian, and so the modules support British English over American English where necessary, with the Oxford English Dictionary as our guide.
