The quality or state of being appetitive; the tendency to have strong desires or cravings.
From appetitive plus the suffix -ness, which converts adjectives to abstract nouns describing the quality itself. This creates a noun form suitable for discussing appetite and desire as general characteristics.
Adding '-ness' to 'appetitive' follows one of English's most productive patterns—we can turn almost any adjective into an abstract noun this way. This particular word feels academic because we rarely say it in everyday speech; 'appetite' does the job much faster!
