This paper aims to present the results obtained in a survey whose objective was to investigate the Iranian French language learner's definition of memorization, and the techniques they adopt most frequently in memorizing linguistic structures and vocabulary. The results indicate that although memorization plays a significant role in learning a foreign language, it is often neglected or understated. Memorization techniques are known to be rather individual, but it is suggested that weak learners can be encouraged to replace old techniques with more effective ones that could pave the way to a profound and stable learning.
