A self-service grocery store, typically smaller or less formal than a supermarket; a casual or informal grocery shopping establishment.
A blend of 'grocery' and '-teria' (from cafeteria, ultimately from Spanish cafe). This 20th-century portmanteau emerged as self-service stores became popular.
Groceteria is a fun example of how English blends words when new things emerge — we did the same with 'brunch' (breakfast+lunch) and 'smog' (smoke+fog)!
