Talk:dceřinný
Acceptance of the spelling
editSSJC does not seem to contain dceřinný - “dceřinný”, in Slovník spisovného jazyka českého (in Czech), 1960–1971, 1989.
The form with double n is in wide use.
The form "dceřinný" is in PSJC - “dceřinný”, in Příruční slovník jazyka českého (in Czech), 1935-1957.
It seems some language engineers (as opposed to language scientists) decided in the years between PSJC and SSJC to declare "dceřinný" incorrect.
There is a certain analogy between dceřinný and rodinný, krajinný, povinný, vinný, stinný and the like. The objection of the engineers is probably that while rodinný and krajinný are derived from terms ending in -na (rodina, krajina) or otherwise having n in the suffix or ending, that is not true of "dceřinný". However, if dceřinný is derived from dceřin (posessive of dcera), there is still a final n to which -ný can be attached, leading to double n. The question remains what other analogues there are of dceřinný, if any.
