Favourite Words

When reading a blog earlier this evening I got to thinking, what are my favourite words? I had noticed when reading a section on geology in Terry Pratchet's book 'Darwin's Watch' that I appreciate the feeling I get when reading the word 'rock.' Rock. It is not much of a word but for some reason I like it. Today when reading a blog by a lady who loves cupcakes, I found I like the feeling of "cupcake" too. It's not a word I would use as it seems to be American, but I do like to read it. The link between the two words appears to be "ck." There is another word along the same lines, but I cannot currently think what it is... Perhaps in the morning.
