@Satsuma No issues with that word... "things having been administered/executed/performed" (perfect active participle, neuter nominative/accusative/vocative plural of Latin administrare, "to administrate, perform, execute"). Go for it!
@greyor oh I realized no one could stop me from inflecting things however I want a long time ago! But it is funny when I share notes with people because it's usually the first section header which makes it especially noticeable
@Satsuma that's awesome! Definitely not as common though and always happy to know fellow Latin nerds 🤓😎
