Welcome! Military words like danegeld and scutage have been reserved for an upcoming list about medieval laws and crimes. Similarly words like centenar, turcopole and mameluke, aside from a few favorite titles, have been saved for an upcoming list about medieval titles and peerages. Likewise for your patience words like portcullis, trebuchet, loophole and other obvious terms have been excluded. Also, terms like cri de coeur and coup de grâce which are brilliant for military applications have been reserved for a separate list about English terms that are clearly not English. I should also mention that words like caliver and baselard, not to mention many pieces of armor, have of course been reserved for future lists about ancient, medieval and renaissance arms and armor. Again, seafaring terms, castle terms and HEMA terms have all been for the most part excluded for the aforementioned reason. At last, enjoy!

I referenced no other list while making this list, which has helped to improve my own memory. All words here were found slowly over time by reading history and historical fiction. Historical fiction, despite my love for fantasy, satiates my predilections like no other genre except, of course, litHEMA.

This list will be updated whenever I come across more related words so if you check back here later it may be weightier and prithee leave a comment if you know a word that could be added!
