The student of Hebrew need master a vocabulary of less than 800 words to have learned all the verbs occurring twenty-five times or more and all other words used more than fifty times in the Hebrew Old Testament. The lists that Dr. Watts has prepared are taken from W. R. Harper's Hebrew Vocabularies, which has been revised and corrected in comparison with Kohler-Baumgartner, Lexicon in Veteris Testamenti Libros.Where a verb occurs in only one stem, this is noted in the Hebrew list. When a verb has different meanings in different stems, this is noted in the English list. Nouns and adjectives from the same root are listed together so that the student may learn to distinguish them immediately. Words are arranged according to the frequency of their occurrence. The author has used these lists in mimeographed form for more than five years in teaching elementary Hebrew to theological students.
