A Superette, is a compact food market "convenience store" or "mini-mart".[1]
The term is most commonly used in the North Island[2] of New Zealand,[3] but also to a lesser extent in Northern New England,[4][5] Newfoundland and Labrador,[6] and elsewhere as an alternative name for a "convenience store" or "mini-mart."
There is a superette in New Orleans, LA called "Terranova Brothers Superette" located at 3308 Esplanade Ave 70119. They have a deli section as well as a small grocery.
The name "superette" is something of an oddity; consisting of a prefix, "super" derived from supermarket, and a suffix "ette" meaning "smaller version of"—but no actual stem.
The quirkiness of the word itself has led to its use by some unrelated groups and businesses:
RCA RADIO MODEL LINE
From 1931 RCA produced a range of small mantel radios called the "Superette"[10][11] - in which case "super" was derived from superheterodyne. Probably the most well known is the Model R7, which was produced in several versions.
RCA also produced an obscure console version the model R9. The R7 and R9 share identical chassis (tubes RCA 280, 227, 235, 245 and 224). There were several versions the R7A using pentode output tubes (RCA 247), R7 and R9 DC for 110 VDC power and the R7 LW for long wave listening. These early superheterodynes had no AVC so stronger stations were louder than weaker ones. RCA also had the R8 Superette as well.[12]
