Talk:improper

In the mathematical phrase improper integral, can it have been derived from a Latin improprius that means not fitting, not touching? In Hungarian (my language) illő (proper, according to customs) and illeszkedő (fitting in place) are derived from the same root. Can improprius in Latin mean something like this? It would make more sense with the integral. Qorilla 12:36, 30 June 2009 (UTC)
