great, thanks. This is even more comprensive than others i have seen.
Thanks for giving the link to such great websites 
Something like this would be such a great reference tool … in making sure that i don’t “miss” a common word as I try to plan out my son’s word list in the future. It’s a whole lot better than me trying to come up with my own new words off the top of my head!
