carp

As a noun, this refers to a specific type of fish. It is a mass noun when referring to the species in general, but can be used as a countable noun when referring to individual fish. Notably, the plural form "carp" is frequently used instead of "carps" when discussing a group of the same species. As a verb, the word carries a negative connotation of petty annoyance. It describes a specific type of complaining that is repetitive and focused on insignificant details, rather than a legitimate grievance. This usage is typically informal and suggests a grating or nagging tone.
