Reconstruction:Proto-Finnic/-inën

Etymology
Two distinct stems that have been conflated into a single paradigm, as per Hakulinen; a case of suppletion.

The oblique stem (sometimes reconstructed as, which is probably secondary) is from , , , , and is cognate with 🇨🇬. The oblique stem is probably original. In many descendants the original nominative can be found in compounds, albeit in reduced form ( > in,  in ,  in ,  in ,  in ,  in ,  in ,  in ). Remnants of the original nominative may be preserved in toponyms ( near Salo in Finland,,  and  in Ingria).

The origin of the nominative is ; it might be related to  (diminutive suffix), in which case the -i- would be analogous to the oblique stem.
