Noun, Anglo-Indian. Alright, it’s not an archival term, but it might be useful for certain kinds of memo. Perhaps it just entered the lexicon at the wrong time! I hope this handy word won’t be killed off by American English.
All the vocabulary in this weekly feature so far has been of Latin or French origin. A variety of Latin was used by officials and academics into the 18th century, and of course archival theory developed in France. That’s not to mention those Anglo-Normans!
