The term EXEMPLAR OF INNOCENCE can be summarized as a 'LAMB', which is a four-letter word. A LAMB is a young sheep, and is often used as a symbol of innocence and purity. In Christianity, Jesus is referred to as the LAMB of God, and in literature, lambs are often used to represent characters who are innocent and naive. Lambs are also seen as gentle and meek creatures, making them an ideal representation of innocence.
