Vocabulary has always been a significant component in foreign language learning (FLL), and it is not surprising that it has attracted the interest of many researchers, especially in the last thirty years. One important aspect, among others, has been ‘vocabulary learning strategies’ (VLS).Ellis (2001, p.554) indicated that VLS is a promising field of investigation since the findings might help to define language learning targets and strategies. Likewise, Hatch and Brown(1995, p.372) remarked that understanding how learners acquire vocabulary and knowing about which methods work better could help teachers in assisting learners in adopting more profitable strategies. Similarly, Nation (1990, p.159) commented that if teachers want to help their learners to cope with unknown words, it would be better to spend more time on VLS rather than spending time on individual words.
