Hi,

I don't know if you would consider this simpler, it is straight from the
documentation for StringCount:

StringCount["The cat in the hat.", WordCharacter ..]

I don't know what you did when turning it into a function, but this:

numwords[s_String] := Length[ReadList[StringToStream[s], Word]]

numwords["The cat in the hat."]

seems to work alright....
