年頃
としごろ · toshigoro · JLPT N1 · noun
age
🎂 年 (year) + 頃 (about) = about-this-many-years, the age range of adolescence
年 means year and 頃 means roughly or about, so としごろ means roughly a number of years old. It refers to the age when people reach adolescence or become marriageable.
年 — grain 禾 over person 人 (oracle bone)
Originally a pictograph of a person carrying a bundle of harvested grain on their back, representing the yearly grain harvest. Because harvests came once a year, the character shifted from meaning 'harvest' to meaning 'year.' The modern form 年 obscures the original 禾 (grain) + 人 (person) structure.
