What's the difference between generate and spontaneous?

Generate


Definition:

  • (v. t.) To beget; to procreate; to propagate; to produce (a being similar to the parent); to engender; as, every animal generates its own species.
  • (v. t.) To cause to be; to bring into life.
  • (v. t.) To originate, especially by a vital or chemical process; to produce; to cause.
  • (v. t.) To trace out, as a line, figure, or solid, by the motion of a point or a magnitude of inferior order.

Spontaneous


Definition:

  • (a.) Proceding from natural feeling, temperament, or disposition, or from a native internal proneness, readiness, or tendency, without constraint; as, a spontaneous gift or proportion.
  • (a.) Proceeding from, or acting by, internal impulse, energy, or natural law, without external force; as, spontaneous motion; spontaneous growth.
  • (a.) Produced without being planted, or without human labor; as, a spontaneous growth of wood.
