Language can evolve by adding new meanings or “senses” to old words. Thus, the word “face” can refer to the body part or the front surface of a cliff. There are several theories regarding how new senses of words arise historically. Ramiro et al. used an algorithmic approach to study 5000 English words taken from a digital historical dictionary that covers word usage from Anglo-Saxon times to the present. They found that one model—nearest-neighbor chaining—predominates, possibly because it minimizes the cognitive costs of communicating new ideas.
