Shillcock et al. found a significant positive correlation between the representationsl spaces of word-form and of word-meaning in English. If this correlation is useful for word acquisition and comprehension, it could be adptive to maximise it. We devise a method to measure word-form similarity that maximises the form-meaning correlation in Spanish. We show that the correlation is present in Spanish too, and find out more about the organization of words in the morpho-phonological representational space.
