large, powerful breed of dog, early 14c., from Old French mastin "great cur, mastiff" (Modern French mâtin) or Provençal mastis, both from Vulgar Latin *mansuetinus "domesticated, tame," from Latin mansuetus "tame, gentle" (see mansuetude). Probably originally meaning a dog that stays in the house, thus a guard-dog or watchdog. Form in English perhaps influenced by Old French mestif "mongrel."

n. A large breed of dog. Often confused to be part of a type of large dogs. The Mastiff is a breed of its own that is sometimes referred to as an "English Mastiff". Other breeds have Mastiff in their informal name such as "French Mastiff" for Dogue de Bordeaux or include Mastiff in their breed names; Tibetan Mastiff or Neapolitan Mastiff. All are different breeds as well as the often confused Bullmastiff.

Mastiff means a large molosser dog. The term "the Mastiff group" or "the Mastiff" has been used synonymously with the term " molosser". For example, the bulldog breeds, the Great Dane, the mountain dogs, the pit bulls and even smaller dogs such as the Boston terrier, may be considered "Mastiff" in this broad sense.
