Understanding the Term "Septuagenarian"
The formal term for a person between the ages of 70 and 79 is a septuagenarian. This word originates from the Latin term septuageni, meaning 'seventy each'. It is one of a series of such Latin-derived words used to denote a person within a specific decade of life. While accurate, the term is quite formal and not commonly used in everyday conversation. For most people, simply referring to someone as being 'in their seventies' is standard and easily understood.
The Lexicon of Age Decades
To understand the full context of the term, it is helpful to see where it fits within the broader naming convention for different age decades:
- Denarian: 10–19 years old
 - Vicenarian: 20–29 years old
 - Tricenarian: 30–39 years old
 - Quadragenarian: 40–49 years old
 - Quinquagenarian: 50–59 years old
 - Sexagenarian: 60–69 years old
 - Septuagenarian: 70–79 years old
 - Octogenarian: 80–89 years old
 - Nonagenarian: 90–99 years old
 - Centenarian: 100–109 years old
 - Supercentenarian: 110 years or older
 
As you can see, the formal naming convention has a long history, but its practical application varies significantly. As we age, these terms, particularly 'septuagenarian' and 'octogenarian,' become slightly more common in formal writing or journalism but remain rare in casual speech.
Modern Perspectives on Aging Language
In recent years, there has been a significant shift in how society and care professionals approach language surrounding aging. Many organizations and experts now advise against using terms that can feel dated or carry negative connotations, such as 'elderly' or 'senior citizen.' The goal is to use person-first, respectful, and neutral language.
Embracing "Older Adult" and Specificity
Many professionals in gerontology and senior care prefer the term "older adult." This phrasing emphasizes the individual's personhood rather than defining them by their age bracket alone. It is a more inclusive and respectful way to refer to individuals in this stage of life. The American Medical Association and the National Institute on Aging both advocate for this language.
Another modern trend is using specific ages when possible to provide greater clarity and avoid lumping a diverse group of people into a single category. For example, instead of broadly stating 'care for older adults,' one might specify 'care for adults over the age of 80.' This approach recognizes that the needs and experiences of a 70-year-old may differ significantly from those of a 90-year-old.
Comparison of Terminology for People in their 70s
| Term | Connotation | Usage | Context | 
|---|---|---|---|
| Septuagenarian | Formal, technical | Less common in casual speech | Scientific or formal writing, journalism, gerontology | 
| Older Adult | Neutral, respectful, person-first | Preferred in care and academic settings | Medical reports, policy documents, respectful conversations | 
| In their seventies | Casual, clear | Most common and straightforward | Everyday conversation with friends, family, and acquaintances | 
| Senior Citizen | Potentially outdated, can carry negative stereotypes | Decreasing in popularity | Formerly common for discounts and benefits, now often avoided | 
| The Elderly | Often carries connotations of frailty, outdated | Generally avoided | Can be seen as a negative, broad label | 
Celebrating the Seven Decades of Life
Focusing on labels can sometimes obscure the richness of life experience that a person brings. The seventies are often a vibrant, active time for many individuals. Freed from the responsibilities of a career, many septuagenarians pursue new hobbies, travel, volunteer, and spend more time with family. This stage of life is a testament to resilience, wisdom, and continued growth. Shifting the focus from labels to celebrating individual accomplishments and passions is a more meaningful way to engage with this age group.
How to Address Someone Respectfully
When speaking with or about a person in their seventies, it's best to prioritize respect and individuality. Here are some key tips:
- Use their name. The most respectful way to address anyone is by using their preferred name. If unsure, a polite salutation like 'Mr. Smith' or 'Ms. Jones' is a safe starting point.
 - Use neutral terms. When speaking generally, 'older adults' is a safe and respectful option. It emphasizes their personhood rather than their age.
 - Avoid assumptions. Do not assume that someone in their seventies is frail, infirm, or incapable. Avoid using patronizing language or a condescending tone.
 - Ask for their preference. If appropriate, you can ask someone how they prefer to be referred to. This shows respect for their individuality and autonomy.
 
As the National Institute on Aging points out, using careful, respectful language is an important part of avoiding ageism and fostering positive relationships National Institute on Aging: Don’t Call Me Old.
Conclusion: More Than a Label
While a person in their 70s is technically called a septuagenarian, this word offers only a glimpse into the broader conversation around aging. The modern approach emphasizes moving beyond simple labels toward more respectful, person-first language. By understanding the formal terminology while also recognizing the importance of individual preferences and positive aging, we can foster a more inclusive and dignified approach to communication across all age groups. It is a reminder that people are defined by their experiences, character, and individuality, not just by the number of years they have lived.
