Sound-symbolic patterns which relate to the perception of size were found to motivate the behavior of English and Japanese speakers in the naming of pre- and post-evolution Pokémon. The current study builds from this finding and investigates which sound-symbolic association speakers of Brazilian Portuguese (BP) employ to name Pokémon characters. Results from 3 experiments show that vowel quality, phonological length and voiced obstruents, usually used to signal differences in size, are used to signal differences in evolution; however, the effects of voiced obstruents are not identical to what was previously observed in the behavior of Japanese speakers. We argue that although there is a universal sound symbolism associated with these sounds and the perception of largeness, its manifestation differs cross-linguistically. To the best of our knowledge, this is one the first experimental research to investigate sound symbolism and the perception of size in BP.
