Stableboy

A groom or stable boy is a person who is responsible for some or all aspects of the management of horses and/or the care of the stables themselves. The term most often refers to a person who is the employee of a stable owner, but an owner of a horse may perform the duties of a groom, particularly if the owner only possesses a few horses.

The word appeared in English as grome c.1225, meaning "boy child, boy, youth"; its origin is unknown. It has no known cognates in other Germanic languages (e.g. Dutch and German use compound terms, such as Stal(l)knecht 'stable servant', or equivalents of synonyms mentioned below). Perhaps it stems from an Old English root groma, related to growan "grow" or from Old French grommet "servant" (compare Medieval English gromet for "ship's boy", recorded since 1229).

The word was originally rather grander in status, as in bridegroom and the socially elevated offices in the English Royal Household of:

The meaning "man servant who attends to horses" is from 1667, although women and girls are often grooms. The verb is first attested in 1809; the transferred sense of "to tidy (oneself) up" is from 1843; the figurative sense of "to prepare a candidate" is from 1887, originally in U.S. politics.

Grooms may be employed in private residences or in professional horse training facilities such as stables, agistment properties and riding academies.

The groom(s) usually clean stables (mucking-out), feed, exercise and groom horses.

A groom in private service is expected to be 'on call' during specified hours in case any member of the employer's family wishes to ride.

Grooms whose employers are involved in horse sports or horse racing are often required to travel with their employers to provide support services during competitions. The services required vary with the type of competition and range from simply ensuring that the horse is ready for the start of the competition to warming the horse up beforehand.
