名字寓意平淡快乐的英文

A name with the meaning of "plain happiness" in English could be "Eudaimonia," which is derived from the Greek word "eu-daimonia," meaning "human flourishing" or "happiness in living according to virtue." It carries a sense of simple and genuine well-being, rather than exaggerated or ostentatious happiness. Another option could be "Zest," which directly implies a lively and unpretentious joy.
