Many dialects show the stem *mōn- in the meaning 'son' (and *mōḷ- in the meaning 'daughter'). These forms certainly go back to *magan and *magaḷ respectively; however, the contracted forms should probably be reconstructed for PSDR, as they are represented not only in Tamil/Malayalam (where intervocalic -g- regularly disappears in some dialects), but in other languages as well, most notably Tulu and Toda. Another irregularity is the development *mag- > mog- that happens in various languages; particularly noteworthy is the development in Kota, where *-a- does not normally lead to -o- in such a context. Since the root's usage was particularly frequent, special irregularities cannot be excluded; however, it is not excluded that we have to deal with a special cluster (maybe even a special phoneme) in this case.
