3.1. Defining “Adulthood”

Adulthood is defined as the period or state of being an adult, or the time in a person’s life when they are considered fully grown and responsible. Grammatically, “adulthood” is an abstract noun and is usually uncountable (e.g., “Adulthood brings new challenges.”).

The word comes from “adult” + “-hood” (a suffix meaning “state or condition”). The term has been used in English since the 17th century to refer both to the state of being an adult and, by extension, to the period in life following childhood and adolescence.

3.2. What are Synonyms of Adulthood?

For “adulthood,” synonyms include both single-word nouns (like maturity) and multi-word expressions (like coming of age). Some are exact or near-exact substitutes, while others are near-synonyms with overlapping but not identical meanings.
