I needed help with Translation Toolkit and stumbled across a word site that had plural English words only. I used it with many of the singular words I could not figure out plurals for http://www.wordsplural.com/
I am a person that speaks 7 different languages and can say; first-handed that English was / is the greatest task to learn. I found this site to have great resources referencing English words and facts, definitely worth a visit.
