Even such an unmetaphorical-sounding word as the verb 'to be' was generated from a metaphor. It comes from the Sanskrit bhu, “to grow, or make grow,” while the English forms ‘am’ and ‘is’ have evolved from the same root as the Sanskrit asmiy “to breathe.” It is something of a lovely surprise that the irregular conjugation of our most nondescript verb is thus a record of a time when man had no independent word for ‘existence’ and could only say that something ‘grows’ or that it “breathes.”4
