[Alteration of Scots flet, inner part of a house, from Middle English, from Old English, floor, dwelling; see plat- in Indo-European roots.]

Online Etymology Dictionary - Cite This Source - Share This
flat (adj.)

c.1320, from O.N. flatr, from P.Gmc. *flataz (cf. O.H.G. flaz "flat, level," O.E. flet, O.H.G. flezzi "floor"), perhaps from PIE *pla- (cf. Gk. platys "broad, flat;" see place (n.)). Sense of "prosaic, dull" is from 1573; used of drink from 1607; of musical notes from 1591, because the tone is "lowered." Flatfish is from 1710. Flat-footed "unprepared" is 1912 U.S. baseball slang, on notion of "not on one's toes; earlier it meant "straightforwardly" (1828), from notion of "standing firmly." Flat-out (adv.) "openly, directly" is from 1932; earlier it was a noun meaning "total failure" (1870, U.S. colloquial). Flatware is distinguished from hollow ware.

flat
1. Lacking any complex internal structure. "That bitty box has only a flat file system, not a hierarchical one." The verb form is flatten. Usually used pejoratively (at least with respect to file systems).
2. Said of a memory architecture like that of the VAX or Motorola 680x0 that is one big linear address space (typically with each possible value of a processor register corresponding to a unique address). This is a Good Thing. The opposite is a "segmented" architecture like that of the Intel 80x86 in which addresses are composed from a base-register/offset pair. Segmented designs are generally considered cretinous.
3. A flat domain is one where all elements except bottom are incomparable (equally well defined). E.g. the integers.
