Historical definition

Periodus is the term of life.

Meaning

Term can mean the appointed extent or limit of a period. The definition concerns life’s temporal span, rather than identifying a medicine or a celestial body.

Use in the book

The Iliaster family also uses term of life and balm-of-life language. Those fuller entries show how duration can be related to different accounts of life and its sustenance. The present short equivalence supplies no number of years.
