In English contract law, an innominate term is an intermediate term which cannot be defined as either a "condition" or a "warranty".
In Hong Kong Fir Shipping Co Ltd v Kawasaki Kisen Kaisha Ltd (1962 2 QB 26) the Court of Appeal of England and Wales first conceived the notion of an "innominate term" This was followed in the case of The Mihalis Angelos (1971 1 QB 174)
