contents We provide new characterizations of Sobolev spaces that are true under some mild conditions. We study modified first order Sobolev spaces on metric measure spaces: $\mathrm{TC}$-Newtonian space, $\hat{\mathrm{TC}}$-Newtonian space, and Gigli-like space. We prove that if the measure is Borel regular and $σ$-finite, then the modified $\mathrm{TC}$-Newtonian space is equivalent to the Hajłasz-Sobolev space. Moreover, if additionally the measure is doubling then all modified spaces are equivalent to the Hajłasz-Sobolev space.
