old age
old age
Noun
This term describes both a specific stage of the human life cycle and the biological process of senescence. It carries a neutral to slightly poignant tone, often associated with themes of reflection, decline, or retirement. While seniority refers to rank or length of service, old age focuses strictly on chronological and biological aging.
Grammatically, this phrase is treated as an uncountable noun. It describes a state of being or a period of time rather than a discrete object. Consequently, it does not have a plural form and cannot be used with indefinite articles like an old age unless modified by an adjective to describe a specific type of experience (e.g., a peaceful old age).
