IPA: /ˌmɛtəˈmɔːfəsɪs/
KK: /ˌmɛtəˈmɔrfəsɪs/
A significant change in form, appearance, or character, often involving transformation, such as in the life cycle of certain animals or in a metaphorical sense.
The caterpillar underwent a metamorphosis to become a beautiful butterfly.
Metamorphosis → It is formed from "meta-" (meaning change) and "morphosis" (from Greek "morphē", meaning form or shape). The word describes a process of change in form or structure, often used in biological contexts to refer to the transformation of an organism.
Think of 'change' ('meta-') in 'form' ('morphē') to remember that metamorphosis means a transformation in shape or structure.
