the cost of this covering cannot be as low as the one already found, DECOMP does

|
|
|
found, scarce+ity becomes the final decomposition.

| 3.6 The lexicon
|
|
|
|
|
|
3.6.1 Development and composition
|
|
|
The present morph lexicon (Hunnicutt, 1976a) contains about 12,000 entries and is
|
|
|
sufficient to analyze at least ten times that number of English words, giving the
|
|
|
|
|
|
correct morph analysis, pronunciation and part(s) of speech.
