noun small tropical flea; the fertile female burrows under the skin of the host including humans
originUncertain. Possibly from a Cariban language term such as Kari'na siko (“chigoe”) (early recorded variant chico), from Proto-Cariban *tikô, or else a West African borrowing such as Wolof or Yoruba jiga (“insect”). The eighteenth century historian Charlevoix refers to them as chique in his 1730 history of Hispaniola.
