The spelling of the word "cockinesses" may seem confusing at first glance. It contains two suffixes ("-iness" and "-es") added to the base word "cocky". The pronunciation of the word is /kɑkiˈnɛsɪz/, with stress on the second syllable. The letter "c" in "cocky" can be pronounced either as /k/ or /s/, which may further confuse the spelling. However, with practice and familiarity, this word can be easily spelled and pronounced correctly.
The word "cockinesses" appears to be derived from the adjective "cocky" + the suffix "-ness" + the plural suffix "-es".
The term "cocky" originated in the 18th century, derived from the noun "cock", which referred to a young male bird, especially a rooster. In this context, "cocky" meant resembling or displaying characteristics associated with a male bird, specifically arrogance, self-assuredness, or overconfidence.
The suffix "-ness" is used to form abstract nouns indicating a state or quality. It is added to adjectives and transforms them into nouns that represent the quality or condition described by the adjective. Therefore, "cockiness" is the noun form of "cocky" and denotes the state or quality of being cocky or displaying cockiness.
