Thin ice there :P do you happen to know the origin of the word kanin? I'd be interested to know whether it was something originating from the Latin canis / dog that got mistranslated, or whether it's just a coincidence.
French has an old word: conin/conil, from "cuniculus", wich also had a sexual meaning. You find it with this double meaning in some Renaissance songs. Modern French "lapin" is said to come from an Iberian word which also gave the portuguese "laparo".
There is the German word Kaninchen, which is a sub type or smaller version of a rabbit (Hase). However, Kaninchen seems to be rather vaguely defined and the distinction is not as clear cut as monkey and ape (at least to me).
