\c Word formulas automatically select the
correct parse (containing the correct
homograph—noun plural suffix)
\c 1. Click tigers in the \t field
\c 2. Choose the Interlinearize (show all
parses) command on the Tools menu
\c 3. Notice the invalid parse
\c 4. Click the Formulas button
\t tigers
\m tiger        -s
\g Felis_tigris -pl
\p n            -nsuf

\c Truly ambiguous (both noun and verb)
\c Formulas eliminate two invalid parses
\t bears         bears
\m bear    -s    bear    -s
\g Ursidae -pl   hold_up -3s
\p n       -nsuf v       -vsuf

\c Each morpheme has a homograph
\c Formulas eliminate the invalid parses
\t bearers
\m bear    -er   -s
\g hold_up -vnzr -pl
\p v       -vsuf -nsuf

\c Basic Shoebox parsing features, such as
the morphophonemic alteration for -ize
(described using \a and \u fields in the
lexical database) are compatible with use
of formulas to select the correct parse.
\t philosophizes
\m philosophy -ize  -s
\g learning   -nvzr -3s
\p n          -nsuf -vsuf

\c When matching this word's parse, word
formula patterns containing the symbols
NounStem and VerbStem are used
repeatedly—this is called recursion.
\t computerization
\m compute   -er   -ize  -tion
\g calculate -vnzr -nvzr -vnzr
\p v         -vsuf -nsuf -vsuf

\c According to the "longest match"
principle, because flower is in the lexical
database, Shoebox doesn't produce the
potential invalid parse flow -er.
Therefore, the formulas aren't even
needed to eliminate it.
\t flower
\m flower
\g plant
\p n

\c Because there is only one parse, which
happens to be correct, it doesn't matter
that it doesn't match any formula
\t admirable
\m admire       -able
\g think_highly -vadjzr
\p v            -vsuf

\c To select the correct parse, another
word formula pattern is needed to
match v followed by vadjzr
\t bearable
\m bear    -able
\g hold_up -vadjzr
\p v       -vsuf
