Select the most appropriate antonym of the given word: Eulogy

The correct answer is Castigation.

Understanding the Given Word:
Eulogy refers to a speech or piece of writing that praises someone or something highly, especially someone who has recently died. Synonyms include praise, acclaim, tribute, and panegyric.

Analyzing the Options:

1. Panegyric: A formal speech or text praising someone or something highly. This is a synonym of "Eulogy", not an antonym.
2. Tributary: A river or stream flowing into a larger river or lake, or paying tribute. This is unrelated to the context.
3. Castigation: Severe criticism or severe punishment. Since "Eulogy" means high praise, "Castigation" (severe criticism) is its direct and most appropriate antonym.
4. Pronunciation: The way in which a word is pronounced. This is unrelated to praise or criticism.

Therefore, Castigation is the most appropriate antonym of Eulogy.
