Disclosure: I am a bit testy and don't feel very accommodating lately. I do not profess to be a grammar expert, but some things are so basic, they should not be written incorrectly, IMHO.
I was blog surfing and reading some recent posts at various sites and ran across a grating misuse of the French word, voila. The blogger incorrectly spelled it as "walla" numerous times throughout her blog, which leads me to believe that she doesn't know that she is wrong. I considered emailing her to let her know, but don't really know how to tell her the appropriate spelling without offending her. To ensure that I am, in fact, correct, I located this definition:
"Walla is a word used by retarded Americans who don't know any foreign languages and barely know their own. The correct word they are looking for is "voila", which loosely translates as "here it is", "there you go", or similar meanings." (UrbanDictionary.com). This is a bit more caustic than I would prefer but does get the point across.
I find that I am increasingly less tolerant as I age.
