Lattice dynamics and magnetic excitations are investigated to elucidate theorigin of magneto-dielectric effects in the S=1/2 two-dimensional quantum spincompound K$_2$V$_3$O$_8$. We find evidence for lattice instabilities at 110 Kand 60 K as optical phonon anomalies and a soft mode at 26 cm$^{-1}$ in A$_1$symmetry. Two-magnon excitations in B$_1$ symmetry show an unconventionaldouble-peak structure and temperature dependence. This suggests the existenceof a split mode near the zone boundary caused by a mixing of spin and latticemodes.
