Isn't an anagram a word game where letters of one word are rearranged
to spell another word or series of words? For instance, an
anagram for 'microwave' is 'warm voice,' one for ''resistance"
is "ancestries," and for "vector" is "covert." If so, then this
puzzle is misnamed; it is really a crossword puzzle. Maybe back
in 1961 the word anagram included this type of puzzle. Regardless
of the naming error, I did learn a new word: "inertance,"
which means "the effect of inertia in an acoustic system, an
impeding of the transmission of sound through the system."
By John Comstock
