Origin: Of multiple origins. Partly a borrowing from French. Partly a borrowing from Latin. Etymons: French pyramide; Latin pȳramid-, pȳramis.
Etymology: < Middle French, French pyramide, †piramide (in architecture) Egyptian funerary monument, building of a similar shape (c1160 in Old French), (in geometry) specific kind of polyhedron (1370), object or arrangement of objects in the shape of pyramid (15th cent.) and its etymon classical Latin pȳramid-, pȳramis (in post-classical Latin also piramis (11th cent. or earlier)) monumental structure built in ancient Egypt and used as a royal tomb, (in geometry) solid figure having the form of such a monument, any structure of this shape, natural object of this form < ancient Greek πυραμίδ-, πυραμίς monumental structure built in ancient Egypt and used as a royal tomb, (in geometry) solid figure having the form of such a monument, of unknown origin (see note). Compare Old French piramz pyramidal shape (1272 in an apparently isolated attestation describing a bird of prey), Catalan piràmide (1617 as piràmida, originally in geometry), Spanish pirámide (1439 cent., originally in geometry), Portuguese pirâmide (late 16th cent.), Italian piramide (1292 describing the shape of a shadow, a1375 in architecture, a1537 in geometry); also Dutch piramide (1566), German Pyramide (1494), both originally in sense ‘Egyptian funerary monument’.Ancient Greek πυραμίς is explained by some ancient authors as a derivative of πῦρ fire (see pyro- comb. form), on account of its pointed shape, by others as < πυρός wheat, grain (see pyrene n.1), as if a granary. Compare ancient Greek πυραμίς kind of cake, which does derive < πυρός wheat, grain; it has been suggested that the word was used to denote an Egyptian monument as having the same shape as the cake, but the shape of the cake is otherwise unknown so this theory remains speculative. The suggested derivation from Egyptian pr-m-us height (of a pyramid) is doubtful. The evidence of verse shows that in the early modern period the word showed plurals of two types: firstly (closely following the morphology of the Latin word) plural forms with stress on the second syllable, which were either quadrisyllabic (as in Latin) or trisyllabic (with the English plural ending -s , -es ) (see α. forms); secondly, plural forms with stress on the first syllable (and with the English plural ending -s , -es ) (see β. forms). In some cases (e.g. the Middle English form piramudes , which is attested only in prose) the assignment to α. or β. forms cannot be taken as definite. The (rare) γ. forms apparently arise from misapprehension of piramis as a plural form, with the form pirami apparently showing an inferred singular. The δ. forms arise from misinterpretation of the α. plural forms as singular. Compare the secondary plural piramidesses in this sequence. With the form pirament compare α. forms at pediment n.
I. A pyramidical structure.

a. Geometry. A polyhedron of which one face (the base) is a polygon of any number of sides, and the other faces are triangles whose bases are the sides of the polygon and which meet at a common vertex. Formerly also: †a cone (obsolete).
