Do individual sounds carry meaning? The relationship between sound and meaning in human languages is typicallyassumed to be arbitrary, though recent research provides evidence for the existence of both iconicity and systematicitybetween word forms and their meaning. However, this research has not asked whether individual sounds in a languagecovary in systematic ways with aspects of meaning. In two analyses, we find evidence for more systematicity betweenthe initial phones of words and those words concreteness ratings than one would expect in a truly arbitrary lexicon. Thissuggests that initial phones may act as cues to aspects of word meaning, and raises questions about whether languagelearners detect and exploit these cues.
