The word "coriander" entered English in the 14th century from Anglo-French coriandre, which came from Latin coriandrum, borrowed from Greek koriannon (also spelled koriandron). The most widely cited etymology connects the Greek plant name to koris (bedbug), based on the idea that the strong, somewhat unpleasant smell of the unripe coriander plant resembled the odour of crushed bedbugs. This derivation, proposed in antiquity by Pliny the Elder, has been both defended and disputed by modern scholars.
Coriander is one of the world's oldest known spices. Seeds have been found in archaeological contexts dating to the 7th millennium BCE in Israel, and the plant appears in Egyptian medical papyri and in the Hebrew Bible, where manna is compared to coriander seed. The Romans brought coriander cultivation throughout their empire, and medieval European herbalists prescribed it for digestive complaints and as an aphrodisiac.
The linguistic split between "coriander" and "cilantro" reflects a fascinating division in English usage. "Cilantro" entered American English from Spanish, where it developed from the same Latin root coriandrum through a different phonological pathway: coriandrum → culantro → cilantro. In American English, "cilantro" typically refers to the fresh leaves and stems, while "coriander" denotes the dried seeds. British English uses "coriander" for both. This terminological split obscures
The genetic dimension of coriander perception has become one of food science's most publicized findings. Studies have identified variations in the OR6A2 olfactory receptor gene that correlate with perceiving coriander leaves as soapy or unpleasant. The aldehydes in coriander leaves — particularly (E)-2-decenal — are chemically similar to compounds produced by some insects, lending indirect support to the ancient Greek association with bedbugs. This genetic variation affects roughly
The Italian word coriandolo deserves special mention because its plural, coriandoli, is the origin of the English word "confetti." During Italian carnival celebrations, sugar-coated coriander seeds were among the sweets thrown at revellers, and when paper substitutes replaced the actual seeds, the name transferred.
In modern global cuisine, coriander occupies a remarkable position as one of the few herbs used extensively in European, Middle Eastern, South Asian, Southeast Asian, and Latin American cooking. This near-universal culinary reach reflects both the plant's adaptability to diverse climates and its ancient, multicontinental cultivation history — a botanical and linguistic traveller whose name may ultimately memorialise the humble bedbug.
