\title Hyphenation Exception Log
\\Barbara Beeton
\endx

\pagexref{hyphenlog}

Below is a list of words that \TeX\ fails to hyphenate properly.
This is the annual update; the list last appeared in 
Volume~8, No.~3, starting on page~266.
Everything listed there is repeated here.

% As expected, there are more instances of missed than of incorrect hyphens.
The first column gives results from \TeX's |\showhyphens{...}|;
entries in the second column are suitable for inclusion in a
|\hyphenation{...}| list.

In most instances, inflected forms are not shown for nouns and verbs;
note that all forms must be specified in a |\hyphenation{...}| list
if they occur in your document.

Thanks to all who have submitted entries to the list.  Since some
suggestions demonstrated a lack of familiarity with the rules of
the hyphenation algorithm, here is a short reminder of the relevant
idiosyncrasies.  Hyphens will not be inserted before the second letter, nor
after the third-from-last letter of a word; thus no word shorter than five
letters will be hyphenated.  (For the details, see \TB, page~454.  For a
digression on other views of hyphenation rules, see below under ``English
Hyphenation''.)  This particular rule is violated in some of the words
listed; however, if a word is hyphenated correctly by \TeX\ except for
``missing'' hyphens at the beginning or end, it has not been included here.

Some other permissible hyphens have been omitted
% from the right-hand entries in this list 
for reasons of style or clarity.  While this is at
least partly a matter of personal taste, an author should think of the
reader when deciding whether or not to permit just one more break-point
in some obscure or confusing word.  There really are times when a bit of
rewriting is preferable.

One other warning: Some words can be more than one part of speech,
depending on context, and have different hyphenations; for example,
`analyses' can be either a verb or a plural noun.  If such a word appears
in this list, hyphens are shown only for the portions of the word that
would be hyphenated the same regardless of usage.  These words are marked
with a `*'; additional hyphenation points, if needed in your document,
should be inserted with discretionary hyphens.

The reference used to check these hyphenations is {\sl Webster's
Third New International Dictionary}, Unabridged.

\beginsection English Hyphenation

It has been pointed out to me that the hyphenation rules of British English
are based on the etymology of the words being hyphenated as opposed to
the ``syllabic'' principles used in the U.S\null.  Furthermore, in the
U.K., it is considered bad style to hyphenate a word after only two letters.

In order to make \TeX\ defer hyphenation until after three initial letters,
some new patterns can be added, as communicated to me my Donald Knuth:

\smallskip
\begingroup
\leftskip=\parindent
%	from message of 03 Oct 88, DEK@Sail to BB@Sail
\noindent
To suppress hyphenation after two letters, you need new patterns
of the form |.ab6| for all pairs of letters |ab| that begin words of English.
I think the number of such pairs is well under 200.
\endgraf
\endgroup

\smallskip
\noindent
Running |PATGEN| on a British, rather than a U.S., dictionary would probably
result in a useful, but smaller, set of patterns, as more ambiguities might
be expected in an etymologically-segmented word base.  This is just a guess;
I would be interested in a report on actual results, if anyone has tried it.
