Shivah, also known as Shiva, is a Hebrew word that refers to the week-long period of mourning observed by Jewish families after their loved ones pass away. The term is often used interchangeably with the word mourning or bereavement, but there are a few synonyms that may be used to describe the same thing. These include lamentation, grieving, and regret. Each word is a poignant reminder of the heavy emotions that come with the loss of a loved one, as they convey deep sadness and sorrow. While the customs and traditions associated with shivah may vary between Jewish communities, the core concept of mourning remains the same.
