Etymology

The term "seven-year-old" is a compound adjective/noun formed by combining the cardinal number "seven," the time unit "year," and the adjective "old." This structure follows a common English pattern for age description (e.g., "five-year-old," "ten-year-old"). The hyphenation ensures clarity, treating the phrase as a single modifier. The logic is straightforward: it literally means "having lived seven years."
