This research investigates sound symbolism: the relationship between particular speech sounds and perceived meanings. By analysing animal names in English, French, and Spanish, it examines whether consonants, vowels, and syllable stress correspond with characteristics such as size and danger, helping explain language evolution and potentially informing language learning and word creation.

This research investigates why children struggle to learn pronouns and why these difficulties vary across languages. Through cross-linguistic experiments and eye-tracking, it shows that pronouns pose an intrinsic processing challenge. Some languages compensate for this difficulty, offering new insights into language development and human learning.
