Tattoo is a loanword from the Samoan word "tatau", meaning "to strike". The "Oxford English Dictionary" gives the etymology of tattoo as "In 18th c. tattaow, tattow. From Polynesian (Samoan, Tahitian, Tongan, etc.) tatau. In Marquesan, tatu." Before the importation of the Polynesian word, the practice of tattooing had been described in the West as painting, scarring or staining. The etymology of the body modification term is not to be confused with the origins of the word for the military drumbeat or performance — see "military tattoo". In this case, the English word "tattoo" is derived from the Dutch word "taptoe".
