We performed ultrasound velocity measurements in the geometrically-frustrated ferrite spinel ZnFe2O4. In the low-temperature paramagnetic phase, the elastic moduli exhibit softening with a characteristic minimum with decreasing temperature. This elastic anomaly suggests the coupling of lattice to molecular-spin excitations.
