1911 Encyclopædia Britannica (1911)
“ DEPUTY (through the Fr. from a Late Lat. use of deputare, to cut off, allot; putare having the original sense of to trim, prune) , one appointed to act or govern instead of another; one who exercises an office in another man’s right, a substitute; in representative government a member of an elected chamber. In general, the powers and duties of a deputy are those of his principal (see also Representation) , but the extent to which he may exercise them is dependent upon the power delegated to him. ”
