For a long time, the process of lexical acquisition in the minds of language learners was explained in part by the idea of associative language learning. The results of L2 research in this area have been less certain so far. It is the goal of this study to delve into some important issues and learn more about how words are stored in the brain—or, to put it another way, how lexical expansion is linked to the process of word association (WA). This study is being conducted to gain a better grasp of how the mental lexicon is linked to lexical semantics, to learn more about how mental links between lexical items in the mental lexicon are established, in line with previous findings, the word associations of native speakers and non-native speakers differ in certain aspects.
