Today Hebrew grammar is well understood and there are many books on it. Rashi, however, lived before the age of grammar books. A major Rashi method is therefore the teaching of basic grammar.

Many students belittle this aspect of Rashi. They erroneously think that because of modern methods we know more. However Rashi will frequently focus on rare grammatical points not covered in conventional textbooks.

There are many classical aspects to grammar whether in Hebrew or other languages. They include
• The rules for conjugating verbs. These rules govern how you differentiate person, plurality, tense, mode, gender, mood, and designation of the objects and indirect objects of the verb. For example how do you conjugate, in any language, I sang, we will sing, we wish to sing, she sang it.
• Rules of agreement. For example agreement of subject and verb, of noun and adjective; whether agreement in gender or plurality.
• Rules of Pronoun reference.
• Rules of word sequence. This is a beautiful topic which is not always covered in classical grammatical textbooks.

Today we deal with the Biblical rules governing indication of a plural direct object. In Hebrew the plural direct object can be indicated by a suffix Mem. For example, Garesh means to expel while GeresheM means to expel them.

Biblical Hebrew also allows use of the suffix Mem-Vav or Tauv-Mem-Vav to indicate the plural direct object. So Gerashtamo also means expel them.

Similarly the Hebrew Lamed-Mem-Vav, Lamo can substitute for the more frequently used Lamed-Hey-Mem, Lahem which indicates the plural indirect object, to them. Examples of this plural indirect object may be found about 5 dozen times in the Bible e.g. in Dt32-32:33,36.
