% =========================================================

% This file takes a practical approach to the hyphenation problem
% which will yield enough correct hyphenations to deal with most
% manuscripts and should not introduce errors. The basic idea is
% the following.
%
% Conversion to lowercase is ambiguous in Greek because of the accents
% which cannot be reproduced, so that (it is hoped) no useful macros
% will use it. We assign the same lccode (1) to all vowels.
% This simplifies (and shortens) greatly the statement of the basic
% vowel\-consonsnt|vowel greek hyphenation rule.
%
% The hyphenation (syllabisation) rules for Greek are quite standard.
% For the monotoniko system, they are listed as follows in the dictionary
% Ôï ÌåãÜëï Ëåîéêü ôçò ÍåïåëëçíéêÞò ãëþóóáò, ôïõ Á. ÃåùñãïðáðáäÜêïõ.
%
% (a) v1\-cv2 is always allowed
% (b) v1\c1c2v2 is allowed when there is a Greek word
%     beginning with c1c2. There are exactly 51 such combinations c1c2
%     in this dictionary, some of them involving only foreign or
%     unusual words.
% (c) v1\-c1c2c3v2 is allowed when there is a Greek word
%     beginning with c1c2 or c1c2c3
% (d) The combinations ìð, íô, ãê do not split
% (e) Compound words obey the same rules
% (f) Diphthongs and other two-vowel combinations which are pronounced
%     as one do not split. These include áé, åé, ïé, õé, ïõ, áõ, åõ,
%     etc.
%
% I am interpreting this to mean that in the other cases splitting is
% allowed, e.g. in the canonical ì\-ì, ë\-ë etc.
%
% To bring the number of cases down to a reasonable few I have combined
% (a), (b) and (c) into the rules "v15cv2", "v13c1c2" and "4c1c2."
% when some word begins with c1c2, together with some of the most common
% cases of "v1c13c2v2" when no word begins with c1c2. I have also added
% ".á4" to inhibit splitting after just one
% letter, something which is done in Greek but is not very pretty, as
% well as "c4." to inhibit splitting with just one letter to go, a rule
% which is implicit above.
%
% These rules still allow some desirable v1\-c1c2c3
% combinations as in óöõ\-ñß\-÷ôñá, and will not introduce
% errors unless there are words which end in three consonants. There may
% be some (presumably) foreign words like this, but I could not think
% of any. The rules may do funny things with foreign words, although
% ðÜñêéíãê e.g., comes out as ðáñ\-êéíãê. I believe (for reasons which
% have nothing to do with mechanical hyphenation) that such words should
% be spelled in the Latin alphabet.
%
% The most glaring incompleteness of these rules is that they do not
% allow for any vowel-vowel splits which are quite common in Greek,
% e.g. çëéêé\-ùìÝíïò. The system does not seem to need these, however,
% and I have been trying it without them.
%
% The choice of 5's and 3's is quite arbitrary and should be reviewed
% after some practice.
