My geeky self would like to add that English is really not a nice language for people with spelling trouble. It's not a phonetic language at all, so there's a lot of room for mistakes (Why "receive", not "recieve", huh? What's the P doing in "receipt"? And why does "eight" have so many letters when you only pronounce three? I'll stop now.) - still, that doesn't mean that disregarding grammar and spelling intentionally makes communication easier at all. And that's what language is usually good for, after all.
I completely agree with this i found and still do find English a really hard language to learn especially plurals. I still haven't got the hang of the them, although i'm a lot better now than i was a few years ago
. As a general rule to me if words sound the same, the plural should be the same too, in my mind anyway.
