I called the super because the heater stopped working.
The super lives in the basement apartment and handles all the trash collection and minor plumbing issues for the tenants.
While the building's owner rarely visits the property, the super maintains a constant presence, ensuring that the aging infrastructure remains functional for the diverse group of residents.
From super- (prefix), from Middle English super-, from Latin super-, from super (“above”). Doublet of over and hyper.
Abbreviation by shortening.
