Firstly, I should like to apologize in advance should anyone be able to point out that braver efforts than mine have appeared in Word Ways before. Still it is not without interest to compare the state of knowledge in (mainly) 1972 with that of today. The common theme among these types of words is that only certain letters are permitted, though not every permitted letter must be used, and more than one copy of each letter is permitted. These words are relatively scarce--roughly one is every thousand words or fewer. Some readers may wish to glance first at the table in the Summary at the end to get an overview. I have indicated hyphens for some words only.
