What is a formal expression of praise for someone, often given at a funeral?

A formal expression of praise for someone, particularly delivered at a funeral, is known as a eulogy. This term specifically refers to the speech or tribute that honors the deceased by reflecting on their life, accomplishments, and the impact they had on others. Eulogies aim to provide comfort to the grieving while celebrating the life and legacy of the person who has passed away.

The other options do not fit this context: a euphemism refers to a mild or indirect word or expression used to replace one that may be found offensive or harsh; extemporaneous suggests something done or spoken without preparation; and to fawn means to exhibit affection or attempt to win favor through excessive praise or flattery. Each of these terms has its own distinct meaning and purpose, which is not aligned with the concept of honoring someone's life at a funeral.
