Morristown, New Jersey
-
Wordlock™, a combination lock using words instead
of
numbers, was created by Todd Basche, a
Silicon Valley executive. Sold by Staples for $5.98 (in blue
or
black)
or
$3.90 (in orange),
it
consists
of
five independently-rotating rings, yielding one hundred thousand different positions,
anyone
of
which the user can select. Because words are more easily remembered than numbers,
he inscribed four
of
the rings with ten different letters each, and the fifth with nine different
letters and a blank, allowing the user to pick either a four-letter or a five-letter word (left column):
MA

With the default factory setting (left column), four
of
the ten combinations can be simultaneously
read
off
as words. Three
of
these, MATCH, BRAIN, and SLEEK, must have been deliberately
created to reside on
the
three raised sections
of
the rings, but DULLY was probably an
afterthought. However, Basche could have rearranged the non-raised letters
on
the rings to spell
TfllNE (or TENSE), ENROL, CODAS and LIST, for a total
of
seven out
often
words.
Rearranging all the lett
er
s on the rings, could Basche have created a full ten words? In other
words, can ten
mutually non-crashing words be found which use the specified letters on the
various rings? (Two words are non-crashing
if
they have no common letters
in
the same position,
such as sTraw and oTher
or
hoUse and brUnt.) The answer
is
yes ten words from the Merriam-
Webster Pocket Dictionary are given
in
the right column above. More generally, a set
of
seventeen mutually non-crashing Pocket Dictionary words can be found on page
211
of
the
author
's
book Making the Alphabet Dance.
Ba
sche apparently consulted letter-frequency tables to select the letters on the rings. Th
commonest ten first letters for four-letter words in the
Pocket Dictionary are SBPTCLDMFR, and
for
fi
ve-letter ones, SCBAPTFGMD--so why did he select J and E for the first ring in preferen e
to
P and
F?
In
the fourth ring, Y
is
rarely found in five-letter words and
is
less common than nin
other letters (SETLDKNMR) ending four-letter ones; R would have been a better choi
e.
Th t P
ten
Pocket Dictionary I,etters terminating five-letter words are EYTRDLNHKS but h I
included S
in
his set
of
nine because
of
noun plurals and verb present tenses. Howe r h
Id
have substituted T for
the
relatively rare
A,
and (possibly) R for H or K.
The most interesting wordplay possibility for Wordlock™
is
found
in
the ord ladd r th
successive transformation
of
one word into another by changing a single I
