On looking at a thing sometimes we say, "It's a torpedo, a lemon, an inkblot, solid, bent, green, and so on", and sometimes we say, "It looks like a torpedo, like a lemon, like an inkblot, solid, bent, green, and so on". Sometimes we say of a person that he saw a torpedo, a lemon, an inkblot, and sometimes we say that he saw something as a torpedo, a lemon, an inkblot.
