different between pyramid vs collection

English

Alternative forms

• piramis, pyramis (obsolete)

Etymology

From French pyramide, from Old French piramide, from Latin p?ramis, p?ramidis, from Ancient Greek ??????? (p?ramís), possibly from ????? (p?rós, “wheat”) + ???? (amá?, “reap”) or from Egyptian pr-m-ws (“height of a pyramid”), from pr (“(one that) comes forth”) + m (“from”) + ws (“height”). Schenkel and K. Lang proposed hypothetical Coptic ????? (piram) or ???? (phram) derived from Egyptian mr via metathesis as a source of ??????? (p?ramís) while Schenkel also suggested it being the source of Arabic ???? although the latter is considered far-fetched by Takacs.
