WiktionaryZ is about lexicology, terminology and ontology. Consequently you would expect that these concepts are in there .. Now they are.
For me not understanding a word and looking up what it means is a moral obligation to include it in WiktionaryZ .. the latest word I did not know was divot. It was used on the BBC news website and yes, you would appreciate what it would be like. The word in Dutch still escapes me :)
