               structures during polarization rotation in relaxor ferroelectrics
               is a long-standing challenge in materials science and
               condensed-matter physics. These nanoscale polar structures are
               characterized by polar nanodomains, which are believed to play a
               key role in enabling the large susceptibilities of relaxors.
               Using epitaxial strain, we stabilize the intermediate step during
               polarization rotation in epitaxial films of a prototypical
               relaxor and study the co-evolution of polarization and polar
               nanodomains. Our multimodal approach allows for a detailed
               examination of correlations between polarization and polar
               nanodomains; illuminates the effect of local chemistry, strain
               and electric field on their co-evolution; and reveals the
               underappreciated role of strain in enabling the large
               electromechanical coupling in relaxors. As the strain increases,
               the competition between chemistry-driven disorder and
               strain-driven order of the polar units intensifies, which is
               manifested in the coexistence of inclined and elongated polar
               nanodomains in the intermediate step of polarization rotation.
               Our findings establish that structural transitions between polar
               nanodomain configurations underpins the polarization rotation and
               large electromechanical coupling of relaxors. Properties of
               relaxor ferroelectrics are governed by polar nanodomains.
               Polarization rotation facilitated by these domains investigated
               by means of epitaxial strain reveals a competition between
