A funeral is the ceremony that is held after someone dies.
(In the UK the dead person is usually buried in a coffin or cremated, and the ashes scattered. The reason I’m mentioning this word is that Elizabeth Taylor’s funeral was held, and her coffin arrived 15 minutes late. She had requested this in her will, in order to fulfil the idiom “She’d be late for her own funeral”. If someone says that someone would be late to their own funeral, they mean that they are always late for meeting or appointments.)
