Subject: [PATCH] word/edit: allow unnamed and/or untranslated entries

Alternative variants can be populated without textual distinction, for
example sexual dimorphism without specific terms, identified by category
override alone.

Probably still a good idea to describe eventually, but this is optional
metadata for visual presentations.
