a representation of a word or phrase by pictures, symbols, etc., that suggest that word or phrase or its syllables: Two gates and a head is a rebus for Gateshead.
2.
a piece of writing containing many such representations.
Origin: 1595–1605; < L rēbus by things (abl. pl. of rēs), in phrase nōn verbīs sed rēbus not by words but by things
1605, from L. rebus "by means of objects," ablative plural of res "thing, object," perhaps principally from the phrase de rebus quæ geruntur "of things which are going on," in reference to the satirical pieces composed by Picardy clerks at carnivals, subtle satires of current events using pictures to suggest words, phrases or things. Or it may be from the representations being non verbis sed rebus "not by words, but by things."
