In this article, I will comment on recent advances in the research on the intersection between language and action. On the basis of the argument proposed by Arbib, I will consider an evolutionary scenario according to which language emerged from a basic imitation mechanism devoted to action representation. I will review more appropriate data in patients who present with gesture and language disorders and add it to behavioral, neurophysiological, and neuroimaging evidence that suggests that specialized sensorimotor circuits underlie action processing and may ultimately even ground complex aspects of language. Finally, in the last part of the article, I will discuss some of the future research on the interwoven processes of production and comprehension that are involved in the predictive mechanisms of action and language.
