*gen(e)-

The core idea of this root was:

giving birth, begetting, “putting into the world”

The family tree is incredibly huge, especially because Latin used the root to express things around birth, inheritance and possession.

Here’s an incomplete list of English members of the family, with some ideas how they tie together:

• gene (from Greek “generation, a people”, then broadened to general idea of class)
• Genesis (Band from the 80s, with Phil f-in’ Collins… Millennials don’t know him, though)
• general (relating to all, the whole people)
• genocide (“killing a people”)
• genealogy (knowledge of family, generations)
• homogenous, heterogenous (of one/multiple types)
• generic (the “baseline” without special features)
• genre (type)
• cognate (same type)
• -gen (nitrogen, hydrogen,… originally: of that type)
• homogeneous, heterogeneous, indigenous
• gender, genus (type)
• genitive (from whom, origin)
• genuine (“from nature, unaltered”)
• engine, engineer (“inherent skill to create”)
• gentle, gentlemen, gentry (originally: high born class, hence noble)
• -geny 
• genital  (stuff you need to create a new generation)
• generate (put into the world)
• genius (“generative power, inner spirit”)
• pregnant, impregnate (“pre birth”)
• Eugene, Eugenie (“well-born”)

• kin (type, family)
• kind (type, family)
• kind (originally “warm feeling toward family”)

• nascent (“being born”)
• nature (“the creation, the universe”)
