An affix is either a prefix or a suffix attached to root words to make other words. For example supply -> supplied by dropping the "y" and adding an "ied" (the suffix).

Here is an example of how to define one specific suffix (the past tense).

D	Y	4
D	0	d	e
D	y	ied	[^aeiou]y
D	0	ed	[^ey]
D	0	ed	[aeiou]y

So this information can be interpreted as follows:

The first line has 3 fields:

1. D - is the name of the character which represents this suffix (affix key)
   
2. Y - indicates it can be combined with prefixes (cross product)
3. 4 - indicates that sequence of 4 affix entries are needed to properly store the affix information

The remaining lines describe the unique information for the 4 affix entries that make up this affix.
Look at the third line:

1. D - is the name of the character which represents this affix (affix key)
   
2. y - the string of chars to strip off before adding affix (a 0 here indicates the NULL string)
3. ied - the string of affix characters to add (a 0 here indicates the NULL string)
4. [^aeiou]y - the conditions which must be met before the affix can be applied (similar to regular expression)
   

Field 4 is interesting. Since this is a suffix, field 4 tells us that there are 2 conditions that must be met. The first condition is that the next to the last character in the word must *NOT* be any of the following "a", "e", "i", "o" or "u". The second condition is that the last character of the word must end in "y".

Let's create one more suffix (the continuous tense).

G	Y	2
G	e	ing	e
G	0	ing	[^e]

Affix keyss can be specified in the word list ([Words] section) by specifying them after the '/' character:


For example:


will associate the 'D' and 'G' flags with the word 'create'.

Words 'created' and 'creating' are "added" to dictionary with our rules!
