english - flag format for English ispell dictionaries
DESCRIPTION
English dictionaries for
ispell(1) supports 3 prefix and 14 suffix flags.
For a detailed description of how
ispell handles flags and capitalization, see
ispell(5) . This manual page only describes flags usable in dictionaries built
using the
english.aff affix file.
In the following discussion of the flags,
let # and @ be "variables" that can stand for any letter.
Upper case letters are constants.
"..." stands for any string of zero or more
letters, but note that no word may exist in the dictionary which is not at
least 2 letters long, so, for example, "fly" may not be produced by placing
the "Y" flag on "f".
Also, no flag is effective unless the word that it
creates is at least 4 letters long, so, for example, "wed" may not be
produced by placing the "D" flag on "we".
In the following list, an asterisk indicates that a flag participates in
cross-product formation (see
ispell(5) ).
