It is shown that the well-known Trudinger-Moser inequality is equivalent to the embedding of the Sobolev space W-n(1,o) (Omega) into the Marcinkiewicz space M(psi), and the function psi is directly defined. It is shown that in the embedding theorem the Marcinkiewicz space M(psi(n)) can not be replaced even by the Lorentz space Lambda(psi(n)) with the same fundamental function.
