This study investigated Iranian English-as-a-foreign-language (EFL) learners’ use of vocabulary learning strategies (VLSs) and its interrelationship with breadth of vocabulary knowledge (VK), depth of vocabulary knowledge and learning styles especially in relation to gender and age. There was a significant relationship between determination VLS and depth of VK. Learning styles of theorist, reflector and activist provided the basis for increasing and improving breadth of VK. Also, there was a significant and incremental (direct) relationship between theorist, reflector & activist learning styles with depth of VK. In three groups of theorist, reflector, and activist learning styles, social VLS provided the basis for increasing and improving breadth of VK. Also, in three groups of pragmatist, theorist & reflector learning styles, there is a significant and direct relationship between memory VLS and breadth of VK. In males group, there was a significant and direct effect between determination VLS and breadth of VK. Furthermore, in females group, there was a significant and direct relationship between social VLS and depth of VK. Considering the age of participants, in the age group of 20-24 years, there was a significant and direct relationship between metacognitive VLS and breadth of VK. However, in the age group of 25-30 years, there was a significant and direct relationship between cognitive VLS and breadth of VK. Given the important mediating effects of gender and age, it is proposed that vocabulary learning be strategically and stylistically integrated into the accumulative process of English learning.
