We'll start off with examining the word "sned," which stumped even the dictionary last time (though it is included in the Scrabble dictionary...).  Synonyms/alternates were listed as "snathe," "sneed," and "snath."  However, it turns out that "sneed" is also nowhere to be found (at least not in any online or print dictionary that I looked in).  Here's what I did find:

SNATH (listed by Dictionary.com as an "unexplained variation of snead" from the 16th century):

The shaft or handle of a scythe.

In addition to the above definition, "snathe" has another meaning, according to Webster's Unabridged Dictionary:

SNATHE (akin to various Germanic words meaning "to cut," such as: Icelandic sneida, German schneiden, Anglo-Saxon besniden, Gothic sneidan, English snath, snithe)

To lop; to prune.

So, it seems that the word has something to do with cutting, possibly crudely rather than precisely, and the word/s is/are no longer used regularly.  Good to know.  Let's continue with some words that we might actually use.

OCTONARY (from Latin octonarius, "containing eight", which is ultimately from the Indo-European root octo, "eight"):

adjective:

1. Of or pertaining to the number 8.

2.Consisting of 8.

3. Proceeding by eight.

noun:

4. A group or set of eight (an ogdoad [wow, another good word]).

5. A stanza of 8 lines

6. A number in an octonary system (I assume from def. 3 above)

Also can be synonymous with OCTAL:

Of or pertaining to a number system with base 8, employing the numerals 0 through 7.

Interesting.

The above definitions are a compilation of the Random House Dictionary (2006) and the American Heritage Dictionary (2006).

I was expecting some good guess for "ignitron," but no one came forth.  Here's what you could've gotten right:

IGNITRON (word used in Electronics, coined in the 1930s from ignite + tron):

A rectifying cathode-arc vacuum tube with an auxiliary electrode projecting into a pool of mercury that conducts current when the anode is positive.

Okay, this issue's words are more useful, and modern, so hopefully there will be plenty of folks who think they know what they mean!

LOGY (also spelled LOAGY)

KRUNK

SCHMOOPY

Good luck - happy guessing!
