We report a phenomenological theory for the kinetic arrest (KA) of a first-order phase transition, taking the Mott metal-insulator transition in V2O3 as a test case. By defining a order parameter ϕ related to the monoclinic distortion of the high temperature metallic and mapping its Time-Dependent Ginzburg-Landau (TDGL) dynamics onto a disorder-influenced Imry-Wortis landscape, we derive a universal transcendental condition for the mechanism of the kinetic arrest. We demonstrate that epitaxial substrate-induced clamping in (001)-oriented V2O3 thin films elevates the elastic activation barriers, trapping the high-symmetry corundum phase down to 4.2~K. This structural suppression of the insulating state robustly explains the observed hysteretic V-I switching a hallmark of memristive behaviour. Our work identifies a "Mott-Glass" as a structurally arrested non-equilibrium state in the strained thin-film of V2O3. Our work provides a predictive framework for engineering strain-tuned neuromorphic synapses.
