A person who is 40 years old is considered a quadragenarian. This term specifically refers to individuals in the age range of 40 to 49.
The term "quadragenarian" is derived from the Latin word "quadrageni," meaning "forty each." It's a way to describe a specific stage of life, just as we use other terms for different age decades.
Here's a table illustrating age-related terms as provided in the reference:
| Age Range | Term |
|---|---|
| 40-49 | Quadragenarian |
| 50-59 | Quinquagenarian |
| 60-69 | Sexagenarian |
| 70-79 | Septuagenarian |
| 80-89 | Octogenarian |
Therefore, if someone asks what age 40 is called, the answer is: a quadragenarian.
