                           LOADING THESE PATTERNS

These patterns, as well  as  those  for  any  other  language, do not become
effective until they are loaded in a special form into a format  file;  this
task  is  performed  by  the  TeX  initializer;  any  TeX system has its own
initializer with its special way  of  being activated.  Before loading these
patterns, then, it is necessary to read very carefully the instructions that
come with your TeX system.

Here I describe how to load the  patterns with the freeware TeX system named
MiKTeX version 2.x for Windows 9x, NT, 2000,  XP;  with  minor  changes  the
whole  procedure  is applicable with other TeX systems, but the details must
be deduced from your TeX system documentation at the section/chapter "How to
build or to rebuild a format file".

With MikTeX:

a) copy this file and replace  the existing file ithyph.tex in the directory
   \texmf\tex\generic\hyphen if the existing one has an older  version  date
   and number.
b) select Start|Programs|MiKTeX|MiKTeX options.
c) in  the  Language tab add a check mark to the line concerning the Italian
   language.
d) in the Geneal tab click "Update format files".
e) That's all!  

For the activation of these  patterns  with the specific Italian typesetting
features, use the babel package as this:

\documentclass{article} % Or whatever other class
\usepackage[italian]{babel}

                           ON ITALIAN HYPHENATION

I have been working on patterns for the Italian language since 1987; in 1992
I published

C. Beccari, "Computer aided hyphenation for Italian and Modern
      Latin", TUG vol. 13, n. 1, pp. 23-33 (1992)

which contained a set of patterns that allowed hyphenation for both  Italian
and  Latin;  a  slightly  modified  version of the patterns published in the
above paper is contained in LAHYPH.TEX available on the CTAN archives.

From  the  above  patterns  I  extracted  the  minimum  set  necessary   for
hyphenating  Italian  that  was made available on the CTAN archives with the
name ITHYPH.tex the version number  3.5  on  the  16th of August 1994.  

The  original  pattern  set  required  37  ops;  being interested in a local
version of TeX/LaTeX  capable  of  dealing  with  half  a dozen languages, I
wanted to reduce memory occupation and therefore the number of ops.

Th new version (4.0 released  in  1996)  of  ITHYPH.TEX is much simpler than
version 3.5 and requires just 29 ops while  it  retains  all  the  power  of
version  3.5;  it  contains  many  more new patterns that allow to hyphenate
unusual words that generally have  a  root borrowed from a foreign language.
Updated versions 4.x contain minor  additions  and  the  number  of  ops  is
increased to 30 (version 4.7 of 1998/06/01).

This new pattern set has been tested  with the same set of difficult Italian
words that was used to test version 3.5 and it yields the  same  results  (a
part  a  minor  change  that was deliberately introduced so as to reduce the
typographical hyphenation  with  hyathi,  since  hyphenated  hyathi  are not
appreciated by Italian readers).   A  new  enlarged  word  set  for  testing
purposes  gets correct hyphen points that were missed or wrongly placed with
version 3.5, although no error had  been reported, because such words are of
very specialized nature and are seldom used.

As the previous version, this new set  of  patterns  does  not  contain  any
accented  character  so  that  the hyphenation algorithm behaves properly in
both cases, that is with cm  and  with dc/ec fonts.  With LaTeXe terminology
the difference is between OT1 and T1 encodings;  with  the  former  encoding
fonts  do  not  contain  accented characters, while with the latter accented
characters are present and sequences  such  as  \`a map directly to slot "E0
that contains "agrave".

Of course if you use dc/ec fonts (or any other real or virtual font with  T1
encoding)  you get the full power of the hyphenation algorithm, while if you
use cm fonts (or any other real or virtual font with OT1 encoding) you  miss
some  possible  break  points;  this  is  not a big inconvenience in Italian
because:

1) The Regulation UNI 6015 on  accents  specifies  that  compulsory  accents
   appear  only  on the ending vowel of oxitone words; this means that it is
   almost indifferent to have or  to  miss  the dc/ec fonts because the only
   difference consists in how TeX evaluates the end of the word; in practice
   if you have these special facilities you get "qua-li-t\`a", while if  you
   miss them, you get "qua-lit\`a" (assuming that \righthyphenmin > 1).

2)  Optional  accents are so rare in Italian, that if you absolutely want to
   use  them  in  those  rare  instances,  and  you  miss  the  T1  encoding
   facilities, you should also provide  explicit discretionary hyphens as in
   "s\'e\-gui\-to".

There is no explicit  hyphenation  exception  list  because  these  patterns
proved  to  hyphenate correctly a very large set of words suitably chosen in
order to test them in the most heavy circumstances; these patterns were used
in the preparation of a number of books and no errors were discovered.

Nevertheless if you frequently use  technical terms that you want hyphenated
differently  from  what  is  normally  done  (for  example  if  you   prefer
etymological  hyphenation  of  prefixed  and/or  suffixed  words) you should
insert a specific hyphenation  list  in  the  preamble of your document, for
example:

\hyphenation{su-per-in-dut-to-re su-per-in-dut-to-ri}

Should you find any word that gets hyphenated in a wrong way, please, AFTER
CHECKING ON A RELIABLE MODERN DICTIONARY, report to the author, preferably
by e-mail.


                       Happy multilingual typesetting !
