blanket term vs genus

blanket term

noun
  • A word or phrase that is used to describe multiple groups of related things. The degree of relation may vary. Blanket terms often trade specificity for ease-of-use; in other words, a blanket term by itself gives little detail about the things that it describes or the relationships between them, but is easy to say and remember. Blanket terms often originate as slang, and eventually become integrated into the general vocabulary. 

genus

noun
  • Within a definition, a broader category of the defined concept. 

  • A taxon at this rank. 

  • A natural number representing any of several related measures of the complexity of a given manifold or graph. 

  • A category in the classification of organisms, ranking below family (Lat. familia) and above species. 

  • A group with common attributes. 

  • A type of tuning or intonation, used within an Ancient Greek tetrachord.
