An update on my previous answer.
It turns out that the "enm" stood for Middle English, so the display was trying to interpret definitions that are generally irrelevant to us. (Wiktionary actually covers a multitude of languages, living and dead.)
I've made a small adjustment, with the aim of excluding those puzzling references to "enm". Hopefully it won't exclude anything that should be there.
I said above "generally irrelevant", because one consequence of the change I've made is that a few extra rare words will come up with no definition available. In some of these cases the definition classed by Wiktionary as Middle English may be the reason the word is accepted in Chi. But I don't think it would be helpful to start including all Middle English definitions.
If anyone spots any further oddities in the definition display, please keep it to yourself let me know.
