The aim of the paper is to examine the changes, which occurred in the epistemological structure of classical mechanics during its development from Newton to Poincaré. The analysis is based on the reconstruction of the language form. Attention is paid to such aspects of the language of classical mechanics as the notion of pace (configurational space, representational space, differentiable manifold, phase space) or the description of action (by force, potential, Lagrangian and Hamiltonian functions). Even though these notions do not have direct denotation, they, nevertheless, constitute the general framework, on which the relation between the denotative descriptions of the language of classical mechanics and the reality is based.
