A document that shows a student is sick, allowing them to miss classes and exams without penalty, and sometimes letting them pass courses they couldn't complete due to their illness.
The student submitted an aegrotat to avoid failing the course due to illness.
Aegrotat is derived from the Latin word "aegrotare" (meaning to be ill or sick). The term specifically refers to a medical certificate or note indicating that a student is unable to attend school due to illness.
Imagine a student who is 'ill' ('aegrotare') and needs a note to explain their absence — that's what an aegrotat is.
