NAME¶
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)).
The meaning of the prefix flags is as follows:
  - *A

    ... --> re... as in cover --> recover
    
   
  - *I
