matryn
/ˈmatrin/ noun- the roll a thing is held to; the account that settles it when memory and intention disagree.
- Aviation. what was flown, taught, and signed — kept in a form that can be answered for, years later, by someone who was not there.
From Late Latin matricula, the small roll: a register read aloud so everyone knew who was on it. We took the word because the roll came first. The flying was only ever the part people could see.
