庚（geng）
Name meaning
庚 (geng) is the seventh heavenly stem and can also refer to age in phrases such as 同庚 (Tonggeng) or 貴庚 (Guigeng). In a given name it is rare and should suggest order, cycles and time-conscious steadiness.
Practical naming use
Use 庚 (Geng) only for a distinctive, classical name that should feel orderly, calendrical and resilient. It suits heritage, chronology, astronomy, history or a person image of steady cycles.
Pairing guide
Pair 庚 (Geng) with clarity, peace or renewal: 庚明 (Gengming), 庚宁 (Gengning), 庚新 (Gengxin) or 庚然 (Gengran). Explain the heavenly-stem context because the character is uncommon in modern given names.
庚明 (Gengming): Geng contributes seventh heavenly stem, firm metal image; Ming adds brightness, clarity.
