Etymology

Origin of metamorphosis

First recorded in 1525–35; from New Latin metamorphōsis, from Greek metamórphōsis “transformation”; equivalent to meta- + -morph + -osis

Explanation

In Kafka's novel entitled Metamorphosis, a man wakes up to find he has turned into a cockroach. That kind of complete and startling change pretty much sums up the word. When a caterpillar becomes a butterfly, it goes through a metamorphosis. An idea can undergo metamorphosis, or metamorphosize, too as can feelings. After you spend a full summer with your grandmother, your feelings about the woman may undergo a complete metamorphosis. While you were once afraid of the old woman, you now love her dearly.
