Iron Heart Tattoo: the beginning of a phoenix chest piece by Joshua Bowers

The word tattoo, or tattow in the 18th century, is a loanword from the Samoan word tatau, meaning "to strike". The Oxford English Dictionary offers the etymology of tattoo as "In 18th c. tattaow, tattow. From Polynesian (Samoan, Tahitian, Tongan, etc.) tatau. In Marquesan, tatu." Ahead of 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.The initial written reference to the word tattoo (or tatau) seems in the journal of Joseph Banks (24 February 1743 – 19 June 1820), the naturalist aboard explorer James Cook's ship HMS Endeavour: "I shall now mention the way they mark themselves indelibly, each of them is so marked by their humour or disposition".[5] The word tattoo was brought to Europe by Cook, when he returned in 1769 from his initial voyage to Tahiti and New Zealand. In his narrative of the voyage, he refers to an operation referred to as "tattaw".

Tattoo enthusiasts may possibly refer to tattoos as "ink", "pieces", "skin art", "tattoo art", "tats" or "work"; to the creators as "tattoo artists", "tattooers" or "tattooists"; and to areas where they function as "tattoo shops", "tattoo studios" or "tattoo parlors".Mainstream art galleries hold exhibitions of both traditional and custom tattoo styles, such as Beyond Skin, at the Museum of Croydon. Copyrighted tattoo designs that are mass-created and sent to tattoo artists are recognized as "flash", a notable instance of industrial design and style.[8] Flash sheets are prominently displayed in many tattoo parlors for the purpose of supplying both inspiration and prepared-made tattoo images to clients.

The Japanese word irezumi implies "insertion of ink" and can mean tattoos employing tebori, the standard Japanese hand method, a Western-style machine or any method of tattooing making use of insertion of ink. The most frequent word utilised for conventional Japanese tattoo styles is horimono. Japanese might use the word tattoo to imply non-Japanese designs of tattooing.
