In reply to:

Yes, Tsk tsk, Tsuwm, ticking off the neophyte about Yarting.

On the one hand, I appreciate that 'tsk tsk' is the standard orthographic convention for this particular expression of sympathy or (in this case) disapproval.

But on the other hand I don't appreciate it one little bit. It took me years as a kid to figure out that the 'tsk tsk' expression I used to read in Disney comics was not pronounced 'tsk tsk' at all, but was in fact that familiar fricative. How on earth and why on earth did that 'k' get in there, Tskuwm?

The real point of course is that 'tsk tsk', however unsatisfactorily it may be spelt, is, I'm delighted and grateful to note... a contranym! (Assuming that it qualifies as a word in the first place. Hmmm.)
