Edwin, Here’s my best shot: How about HYPERNYM and HYPONYM.
HYPERNYM/HYPERONYM/SUPERORDINATE: A word that has a more general meaning than another; e.g. in the relationship between chair and furniture, ‘furniture’ is a hypernym; in the relationship between horse and animal, ‘animal’ is a hypernym (‘superordinate dates from the 17th century, couldn’t find date for hyponym, but would assume 1950s as below)
HYPONYM: A word that has a more specific meaning than another; e.g. in the relationship between chair and furniture, ‘chair’ is a hyponym; in the relationship between horse and animal, ‘horse’ is a hyponym. [this is a relatively new first appearing in the early 1960s as a backformation of ‘hyponomy,’ which itself appeared in the early 1950s (Random House Unabridged Dictionary)
Note: some of these words only appear in ‘some’ dictionaries
