What do the abbreviations L.E., L.C., and D.N.I. mean in Argentinian Spanish? They seem related to car registrations.
Acording to Wikipedia:
Documento Nacional de Identidad or DNI (which means National Identity Document) is the main identity document for Argentine citizens, as well as temporary or permanent resident aliens.
Before the introduction of the DNI in 1968, women had a Libreta cívica [LC] ("civic booklet"); men a Libreta de enrolamiento [LE] ("(military) enrollment booklet").
