I recently saw this video by Matt Parker, giving details on the relationships between various imperial units.
Here is the transcription of his words, as shown on screen:
“.. a cubit divided into thirds gives you a shatments, Why wouldn’t you call something a shatments? If you take five shatments you get a pace...”
This seems to correspond to what he is saying.
Reading this, you would think that shatments would have to be the singular and the plural.
References to this video are now all over the internet so if you google “shatments” you will end up looking at Matt Parker’s words.
I can’t find this word in the OED or in other dictionaries. I’ve tried alternative spellings (shatmence, chatments, eschatments.
Probably the closest is escheatments, which doesn’t refer to a unit of length.
Any clues? Did he just make it up as a dare that he could popularise a nonsense word?
