The letter vav represents conjunction, wholeness, transformation.
The letter vav represents a connection. It joins multiple and even opposite concepts. It represents the link between heaven and earth, and it is shaped like a hook.
Vav joins words to form sentences: it joins sentences to form paragraphs; it join paragraphs to form chapters, it forms chapters to form books.
The absence of vav at the beginning of a new chapter of the Torah indicates the beginning of a new era or a new subject.
Vav implies a relationship between events and continuity of generations.
Vav at the beginning of the word has several possible meanings:
Vav conjunctive (vav hahibur, literally "the vav of connection"—hibur means "joining, or bringing together") is a vav connecting two words or parts of a sentence; it is a grammatical conjunction meaning 'and' , cognate to the arabic. This is the most common usage.
Vav consecutive (vav hahipuh, literally "the vav of reversal"—hipuh means "inversion"), mainly biblical, commonly mistaken for the previous type of vav; it indicates consequence of actions and reverses the tense of the verb following it: when placed in front of a verb in the imperfect tense, it changes the verb to the perfect tense. For example, yomar means 'he will say' and vayomar means 'he said'; when placed in front of a verb in the perfect, it changes the verb to the imperfect tense. For example, ahavtah means 'you loved', and ve'ahavtah means 'you will love'.
