  Computer model has been extensively adopted to overcome the time limitation
of language evolution by transforming language theory into physical modeling
mechanism, which helps to explore the general laws of the evolution. In this
paper, a multi-agent model is designed to simulate the evolution process of
language in human settlements, with the network topology being lattice. The
language of each node in the lattice will evolve gradually under the influence
of its own fixed evolutionary direction and neighbors. According to the
computational experiment results, it is discovered that the state points of
languages always converge into several clusters during evolution process, which
gives us an insight into language evolution.
