                      van der Waals antiferromagnetic FePS3 (Néel temperature
                      TN∼ 120 K) with perpendicular anisotropy. Above TN, while
                      the dielectric response function along the c axis shows
                      frequency-dependent relaxations, in-plane data is frequency
                      independent and reveals a deviation from
                      phonon-anharmonicity in the ordered state, thereby implying
                      a connection to spin-phonon coupling known to be indicative
                      of onset of magnetic ordering. At low temperature (below 40
                      K), atypical anomaly in the dielectric constant is
                      corroborated with temperature-dependent dc and ac
                      susceptibility. The magnetodielectric response across this
                      anomaly differs significantly for both in-plane and
                      out-of-plane cases. We have explained this in terms of
                      preferential orientation of magnetic antiferromagnetic
                      zigzag alignment, implied by the in-plane structural
                      anisotropy as confirmed by ab initio calculations.
                      Controlling the relative strength of magnetodielectric
                      coupling with magnetic anisotropy opens a strategy for
                      tracking subtle modifications of structures, such as
                      in-plane anisotropy, with potential applications for
                      spintronic technologies.},
