Research has shown that prompting learners to elaborate on the appropriateness of form-meaning links can be an efficient vocabulary learning exercise (Deconinck, Boers & Eyckmans, 2017). In this paper we wish to shed more light on the mental processes that occur during this specific elaborative task by investigating the influence of individual learner variables pertaining to prior linguistic knowledge and a number of word-specific features. To this end fifty Dutch-speaking EFL learners rated the congruency they perceived between the form and meaning of 24 English words on a 6-point Likert scale. The motivation of their scores was elicited by means of a think-aloud protocol, the transcriptions of which were analysed with regard to the type of elaborations made. Vocabulary size tests and a language background questionnaire provided us with additional information about the learners. We identified five types of elaborations: cross-lexical associations, sound-symbolic associations, word-form comparisons, morphological associations, and idiosyncratic associations. The data also reveal that the individual learner variables and word-specific features examined in the present study have an influence on the number of elaborations made by the learners. Saussure (1959) claimed, the relationship between form and meaning in language is not entirely arbitrary. In this light, they strive to find motivation in language, which entails that a retrospective explanation can be found as to why a certain word has a particular meaning for example (Radden & Panther, 2004). From a vocabulary learning perspective, once an L2 learner finds a word to be linguistically motivated, it should be easier for said learner to remember this word. This is explained by the fact that considering the connection between a particular word form and its meaning creates a memory trace which facilitates recall of this word (Deconinck, Boers, & Eyckmans, 2010, 2017. The notion of linguistic motivation thus provides learners with an opportunity to develop a new strategy of thinking about why word form and word meaning fit, and consequently employ this technique as a mnemonic method for remembering new L2 words generally (Beréndi, Csábi, & Kövecses, 2008;Boers & Lindstromberg, 2008a;Deconinck et al., 2017).The present paper investigates a form-meaning-fit motivation task, which is a task that encourages L2 learners to consider 'the form-meaning fit' of a new word, i.e. to consider how well the form of the word matches its meaning (Deconinck et al., 2010;Deconinck, Boers, & Eyckmans, 2014;Deconinck et al., 2017). This type of activity stimulates learners to produce associations, or rather elaborations between form and meaning. Deconinck et al. (2014) demonstrated that learners made four different types of form-meaning associations during the form-meaning-fit motivation task. We aim to determine whether the same associations can be discerned when employing the same method, but working with a different set of words and a different group of L2 learners. Analysis ...
