秋 is a bound morpheme (b.f.) that primarily means 'autumn' or 'fall' and forms common compounds such as 秋天 (autumn), 中秋 (Mid-Autumn Festival), and 秋收 (autumn harvest). In literary Chinese it can also mean 'year' or 'time' (e.g., 千秋 'a thousand years'), and it is a common surname. As a bound form, 秋 almost always attaches to another character to form a word.
