The study of fixed expressions contributes to a significant demand of L2/SL teaching, the lexicon acquisition. The binomial language/culture gained a clear shape in the context of L2/SL teaching, so as to require the teacher to reflect constantly on the topics that outline the linguistic and cultural identity of the target language. Based on the assumption that time and culture are inseparable, the PFL/PL2 (Portuguese as a Foreign/ Second Language) teacher has to be prepared to address the Brazilian concept of time. Relying on the notion of time language (HALL, 1996), this study seeks to identify aspects of the Brazilian temporal language. As fixed expressions have different types, it is often difficult to maintain theoretical boundaries among them. Considering Silva's definition of proverb (1999:14-15), some Brazilian popular sayings concerning time were selected. It was found that popular wisdom has at least two types of expressions that refer to time: those related to the concepts of clock time and the ones linked to the concepts of event time (LEVINE, 1997). It is intended therefore that this study may assist the PFL/PL2 teacher in addressing this issue.
