What is the term for a formal expression of disapproval?

The term "citation" typically refers to the act of quoting or referencing a source, particularly in academic or legal contexts, rather than serving as a formal expression of disapproval. A more fitting term for a formal expression of disapproval would be a "critique," as it involves a detailed analysis and judgment of a subject, often indicating faults or shortcomings.

In contrast, a "recommendation" is generally a suggestion for action, while a "comment" can be merely an observation without any formal disapproval implied. Therefore, understanding that a critique is more aligned with formal disapproval helps clarify the correct term related to disapproval within the context provided.
