II. Word count (How many words in the SPECIALIST Lexicon)?

• The word count is the count for different words.
• By Definition, a word has part of speech, inflections, and meaning.
  • saw|noun|E0054443 is a different word from saw|verb|E0054444 and saw|verb|E0055007
  • All words with different categories and inflections are considered as different words. However, words with inflection of "base" could be duplicated words and should not be counted twice for categories of adj, adv, verb, aux, modal, and verb (also pres1p23p). The table below illustrates the duplicated cases for inflection of "base".

    Category	InflVar - Inflection	Unique word?	Notes
    compl (8)	base (1)	true
    conj (16)	base (1)	true
    det (32)	base (1)	true
    prep (256)	base (1)	true
    pron (512)	base (1)	true
    adj (1)	base (1)	false	positive (256) = base (1)
    adv (2)	base (1)	false	positive (256) = base (1)
    verb (1024)	base (1)	false	infinitive (1024) = base (1)
    	pres1p23p (262144)	false	infinitive (1024) = pres1p23p (262144)
    aux (4)	base (1)	false	infinitive (1024) = base (1)
    	have - pres123p (2048)	false	have: infinitive (2014) = pre123p (2048)
    modal (64)	base (1)	false	pres (2097152) = base (1)
    noun (128)	base (1)	false	singular (512) = base (1), e.g. paper, fish, sheep plural (8) = base (1), e.g. police, fish, sheep

• For the corpus without information of categories and inflections, only the spelling (forms) are taken into consideration, such as in n-gram set.
