We employ NMR techniques to investigate the nature of Mn spins in the I-II-V diluted magnetic semiconductor Li(Zn${}_{1\ensuremath{-}x}$Mn${}_{x}$)P ($x=0.1$, Curie temperature ${T}_{C}=25$ K). We successfully identify the ${}^{7}$Li NMR signals arising from the Li sites adjacent to Mn${}^{2+}$, and probe the static and dynamic properties of Mn spins. From the NMR spin-lattice relaxation data, we show that the Mn spin-spin interactions extend over many unit cells.
