We present an analysis of the kinematic and morphological structure of the nebula around the LMC LBV candidate S 119. On HST images, we find a predominantly spherical nebula which, however, seems to be much better confined in its eastern hemisphere than in the western one. The filamentary western part of the nebula is indicative of matter flowing out of the nebula's main body. This outflow is evidenced by our long-slit echelle spectra. They show that, while most of the nebula has an expansion velocity of 25.5 km s-1, the outflowing material reaches velocities of almost 140 km s-1, relative to the systemic one. A ROSAT HRI image shows no trace of S 119 and thus no indications of hot or shocked material.
