Other forms: mourners
Anyone who is grieving for a person who has died is a mourner. Funerals give mourners the opportunity to remember and say goodbye to a loved one.
While a mourner is anyone who mourns someone's death, the word is often used to mean "person attending a funeral." In some cultures, throughout history, professional mourners were people who were hired to publicly display their grief at the funeral of some well-known figure. Today, most mourners are family members and friends — people who knew the person well and grieve their death.
