A putto is often called a cherub (plural cherubs) although unlike the Biblical cherub (plural cherubim) in form and symbolism: cherubim have four faces of different species and several pairs of wings, and are sacred, whereas putti are secular and represent a non-religious passion.
(The term stallion for an uncastrated male horse dates from this time; stallion = stalled one.) Stallion is also used to refer to males of other equids, including zebras and donkeys.
(Contrary to popular misuse, the word colt refers to a young male horse only.) Though many amateur horse owners may simply breed a family mare to a local stallion in order to produce a companion animal, most professional breeders use selective breeding to produce individuals of a given phenotype, or breed.
