Assume we define the locality of a theory as following: Asumme we have a theory of real scalars, so this theory is *non local* if the action has terms like $$\int d^dx\phi(x)V(x-y)\phi(y)$$, and if the action does not have such interaction terms that is a product of the fields at different positions, the action is local. So given this definition of locality assume a local free theory in continuum as, $$S_{cnt}=\int dx^d (\partial_\mu\phi)^2$$ and in the lattice formulation, it becomes, $$S_{lat}\propto\sum_{n\mu} \phi(na)(\phi(na+\mu)+\phi(na-\mu)-2\phi(na))$$ so if lattice spacing $a\to 0$ lattice action would converge to continuum action. My question is: Are the terms $\phi(na)\phi(na+\mu)$ breaks the locality, with respect to the definition I have just provided?
