This paper argues for the integration of the extended mind view and the embodied-grounded view of cognition and language. To this purpose, the idea of “Words As social Tools” (WAT) is put forth. Specifically, the paper suggests that words, can be conceived as quasi-external devices that extend our cognition, one reason for this lying in their social and public character. Moreover, words function like tools in that they enlarge the bodily space of action thus modifying our sense of body. The paper thus reviews the relevant literature on tool-use and on words as tools and reports on recent evidence indicating that word use leads to an extension of space close to the body. As a second step, a model is outlined so as to account for the neural processes that may underpin bodily space extension via word use and may reflect possible effects on cognition of the use of words as external means.
