Sporadically comes from the Greek word sporadikos, meaning scattered, with the root word spora, which means sowing. Imagine sowing seed by scattering it, and you'll get the hit-or-miss sense of sporadically. There is no pattern to the frequency of an event that occurs sporadically. Working sporadically is hard because you lack a steady income and never know when you'll be busy, but traveling sporadically can be fun.
