How to Pronounce Trenny
Pronounced TREN-ee /ˈtrɛn.i/Medium
Meaning: Trenny reads as a diminutive of Trena, itself a short form of Katrina or Catherine, so it traces to the Greek Katharos, meaning pure. The -y ending gives it a cozy, mid-century nickname feel, and it may in some cases stand alone as an affectionate coinage.Low

History & Origin
Trenny is best understood as a diminutive of Trena or Katrina, short forms of Catherine, which comes from the Greek Katharos, meaning pure. Cozy -y nicknames like Trenny were often written straight onto birth certificates in the middle of the twentieth century. It appears only briefly in United States records around the late nineteen-sixties, more a warm pet name than an established given name.
It was never common, touching the records for just a few years and a couple dozen girls at most, so a Trenny from then would be in her fifties today. It reads as an affectionate, homey coinage that never settled into wider use.
