Q words, hearts and dogs

I commented on the lack of "u" after "q" in Arabic words, and a friend of mine pointed me to a Wikipedia article on English words where "q" is not followed by "u." The article lists 16 plus plural words suitable for Scrabble where no "u" is required--a very "u"seful thing to know. The article also points out that other than trade names or proper nouns, these are imports from other languages.
Back to the original subject of dogs, I learned that the romanized Arabic "q" which can be "q" or "k" (as in Koran) needs to be carefully differentiated in writing and speaking, since the word for "heart" (qalb) is very similar to the word for "dog." (kalb) In light of the comforts we get from dogs, it's only fitting to mix them up with hearts .
