Helicity-resolved Raman spectroscopy reveals dynamical coupling between charge-density-wave amplitude fluctuations and symmetry-distinct phonons in a ferroaxial van der Waals crystal. This resonant dressing amplifies the material’s planar chiral lattice response through the underlying electronic order.
