Contingent – Chapter 9 | The normality we’ll never have

normal (adj.)

c. 1500, “typical, common;” 1640s, “standing at a right angle,” from Late Latin normalis “in conformity with rule, normal,” from Latin normalis “made according to a carpenter’s square,” from norma “rule, pattern,” literally “carpenter’s square,” which is of unknown origin (see norm). Meaning “conforming to common standards, usual” is from 1828, but probably older than the record [Barnhart].
