     …, to give, to grant, to let do anything, has been employed as a casual particle, and changed into vi and pi (or bi) as a result of combination.

     e.g. seyay+…=seyyavi-seyvi, to cause to do.

     padippa (=padikka)+…=padippavi-padippi, to cause to learn or read.

     u––a+…=u––avi-u––uv…-u–bi, to feed.

     Many languages have changed from a highly inflexional type to one which is to a considerable extent compounding or monosyllabic, during their Analytical Stage. This may be due to either simplification or decomposition and not to development. Therefore, it is to be known, that monosyllabic stage may be either the earliest or the latest stage of a language, in the history of its formation and existence.
