So, this is a topic that is forever a source of consternation. I have learned to live with it and ignore it. Palmy a common word? Maybe across the pond, not in the US. I missed it, but that's OK; I do not suggest it has to be common in all English speaking countries to be common. I have learned to play "lino" which is a term virtually unused in the US, and tyre = tire, etc. What I wish is an asterisk on common word counts to indicate there is one or more common words therein which are not universally common. Too much to ask for, I am sure, and it still wouldn't necessarily help anyone. Oh well.....
