Each of the words an, am, at, come, rate
and many others can be transformed into a new valid word by adding a prefix be
The following list consists of 16 words, which may be sorted into 4 groups, each of 4 words fitting the same two-letter prefix, specific for that group.
One such group needs KN
as a prefix.
Other 2-letter prefixes are up to you to find.
All 16 words must be used.

Charlie, I wanted to write you a short note about the validity of the
word KNOUT , but after reading DM's post , I have very little to add. The word
is of Russian origin, means "whip"
and is in common use, pronounced knoot (non-silent k, like in kite). It
is accepted by many dictionaries , inter alia Britannica, Oxford,
M-W et al.
Btw, I master Russian on the level of my English and can testify that
there is no synonym describing whip (in English there are several- look it up!
While creating a word puzzle I
always try to introduce some new words, not necessarily esoteric but
not-so-commonly used. Quirk and knout in
our case are such words, adding some educational value to the process
DM, re: knout – I agree with your remark.
Actually, this is the only thing that I agree.
In regard of multiplicity of possible classifications:
a. Nowhere I imply the existence of one
The solver is requested to provide a 4x4 classification, fulfilling certain demands (see Charlie's solution,
mentioning 2 variants, - might be more!). There is no warning like
"provide the solution and prove there are no others", which is
sometimes a basic demand in math problems and totally redundant and even impossible in word problems. If I were
to place a disclaimer regarding quantity of qualifying solutions it would be:
"Since the riddle was created bottoms up - there might be answers beside
the original one . If you find them ,OK -
THE MORE THE MERRIER
Charlie's programs provided unexpected solutions on several occasions .
b. You claim that there probably 4 possible solutions,
I believe there exist much more, but you
provided at most one correct answer: in
BRAVE & KNAVE create a contradiction
I did not bother to check the second, leaving this task to you.
c. Two pieces of advice:
your skills (which I hold in high esteem) towards accuracy in solving rather
than nitpicking i.e. trying to find
faults, real or imaginary.
*Use the rating system by the relevant criteria:
creativity, innovation, interest, is it challenging or not, does it broaden solver's
knowledge and if you do it you will
find that "4 groups of 4" puzzle deserves mark much higher than 2.
If you have other parameters of evaluation, I would like to know them.
