When using the Word Forms Custom, this controls whether to
remove a trailing vowel, or one of a trailing double consonant pair,
after normal suffix processing is finished. This will not apply if it
would take the word below the minimum word length.
For example, if ing is in the suffix list and
Default Removalis Y, then the word running will
have the ing stripped, and then the 2nd n will be
removed via Default Removal, producing run.
Default Removal is set to Y when using Any Word Forms, but not
with Plurals & Possessives.
