Bandolier

Meaning: Ammunition belt, although originally it meant anything worn across the shoulder 'scarfe wise'. This leaves the hands free, hence - presumably - the popularity with mountaineers and rifleers.

Ottoman Bandolier: I'd like one. 

Logofascination: 2. Etymologically it's 'little band*'; a word that has wandered through German, Italian, Spanish and into English via French (but sometimes straight from Spanish). Its meaning shifted to ammunition container quite quickly, perhaps not surprising in 17th century Europe.

In the wild: Hardly wild, but we're still in the Viennese museum of Arms and Armour. I discovered that the gorgeous bag I was coveting was, in fact, a bandolier and have been meaning to look up the etymology ever since.

Usefulness: 3. More useful is Cotgrave's bandouillier, one who wears anything 'scarfe wise'. I do this a lot.



*not related to bandit, which is someone who is banned. 

Chamfron

Meaning: a horse's head-armour, or as Cotgrave has it:

the front-stall, head-peece, or forehead-piece, of a barbed horse. 

Bonus word: a horse's armour is bard(ing), although no-one's quite sure why. This has since extended to the practice of wrapping bacon around poultry when roasting; good to see a useful word so deliciously recycled.

Logofascination: 2. Partly due to the 'there's a word for everything' factor, and partly because of the wide and wild variety of the spelling. I had it written down as chanfron, and Wikipedia has chanpron, but ngrams finds that chamfron is most popular (using the word popular quite loosely) and the OED only gives us chamfron or chamfrain.

In the wild: The Viennese museum of Arms and Armour, back in 2011. I told you I hoard words; I thought it was time to get onto my back-catalogue. It also turns up in Cotgrave, who I do recommend browsing.

Usefulness: 4, unless you're writing historical fiction, or touring an armoury museum.

Ushabti

Meaning: an Egyptian word - a figurine of a dead person, buried with them to do their chores in the afterlife.

Usefulness: 1 (I might be confusing the word with the thing here, but I don't see why you should have to be dead to have an ushabti, and of course it makes a nice, subtle insult for the workplace*)

Logofascination: 3
