We present a far-infrared magneto-optical study of the gapped nodal-linesemimetal ZrSiS in magnetic fields $B$ up to 7 T. The observed field-dependentfeatures, which represent intra- (cyclotron resonance) and interbandtransitions, develop as $\sqrt{B}$ in increasing field and can be consistentlyexplained within a simple 2D Dirac band model with a gap of 26 meV and anaveraged Fermi velocity of $3\times10^{5}$ m/s. This indicates a rather narrowdistribution of these parameters along the in-plane portions of the nodal linein the Brillouin zone. A field-induced feature with an energy position thatdoes not depend on $B$ is also detected in the spectra. Possible origins ofthis feature are discussed.
