  • grammatical meaning — the meaning of an inflectional morpheme or of some other syntactic device, as word order.
  • grandfather's clock — a pendulum floor clock having a case as tall as or taller than a person; tall-case clock; long-case clock.
  • grandmother's clock — a pendulum clock similar to a grandfather's clock but shorter.
  • gravitational field — the attractive effect, considered as extending throughout space, of matter on other matter.
  • great wall of china — a system of fortified walls with a roadway along the top, constructed as a defense for China against the nomads of the regions that are now Mongolia and Manchuria: completed in the 3rd century b.c., but later repeatedly modified and rebuilt. 2000 miles (3220 km) long.
  • great-grandchildren — a grandchild of one's son or daughter.
  • gregorian telescope — a telescope similar in design to the Cassegrainian telescope but less widely used.
  • gulf of carpentaria — a shallow inlet of the Arafura Sea, in N Australia between Arnhem Land and Cape York Peninsula
  • half wave rectifier — A half wave rectifier removes the negative component of an alternating signal leaving only the positive part.
  • half-wave rectifier — a rectifier that changes only one half of a cycle of alternating current into a pulsating, direct current.
  • halt and catch fire — (humour, processor)   (HCF) Any of several undocumented and semi-mythical machine instructions with destructive side-effects, supposedly included for test purposes on several well-known architectures going as far back as the IBM 360. The Motorola 6800 microprocessor was the first for which an HCF opcode became widely known. This instruction caused the processor to read every memory location sequentially until reset.
  • hamiltonian problem — (computability)   (Or "Hamilton's problem") A problem in graph theory posed by William Hamilton: given a graph, is there a path through the graph which visits each vertex precisely once (a "Hamiltonian path")? Is there a Hamiltonian path which ends up where it started (a "Hamiltonian cycle" or "Hamiltonian tour")? Hamilton's problem is NP-complete. It has numerous applications, sometimes completely unexpected, in computing.
  • handlebar moustache — a man's moustache having long, curved ends that resemble the handlebars of a bicycle.
  • haul over the coals — a black or dark-brown combustible mineral substance consisting of carbonized vegetable matter, used as a fuel. Compare anthracite, bituminous coal, lignite.

  • heptachlorobiphenyl — (organic compound) Either of twenty-four isomers of the polychlorinated biphenyl containing seven chlorine atoms.
  • hermetically sealed — airtight
  • hexafluoroplatinate — (chemistry) The univalent anion PtF6- prepared by reacting platinum hexafluoride with certain metals or other elements.
  • horizontal encoding — (processor)   An instruction set where each field (a bit or group of bits) in an instruction word controls some functional unit or gate directly, as opposed to vertical encoding where instruction fields are decoded (by hard-wired logic or microcode) to produce the control signals. Horizontal encoding allows all possible combinations of control signals (and therefore operations) to be expressed as instructions whereas vertical encoding uses a shorter instruction word but can only encode those combinations of operations built into the decoding logic. An instruction set may use a mixture of horizontal and vertical encoding within each instruction. Because an architecture using horizontal encoding typically requires more instruction word bits it is sometimes known as a very long instruction word (VLIW) architecture.
  • horsehair toadstool — a small basidiomycetous fungus, Marasmius androsaceus, having a rusty coloured cap and very slender black stems. It is related to the fairy ring mushroom, but is commonly found among conifers and heather
  • hydrochlorothiazide — a crystalline, water-insoluble powder, C 7 H 8 ClN 3 O 4 S 2 , used as a diuretic and in the treatment of hypertension.
  • hydrostatic balance — a balance for finding the weight of an object submerged in water in order to determine the upthrust on it and thus determine its relative density
  • hyper-nationalistic — a person devoted to nationalism.
  • hyperbolic cosecant — a hyperbolic function that is the reciprocal of hyperbolic sine
  • hypercholesteraemia — (medicine) An abnormally high level of cholesterol in the blood.
  • hyperfocal distance — the distance, at a given f number, between a camera lens and the nearest point (hyperfocal point) having satisfactory definition when focused at infinity.
  • hyperphosphorylated — Simple past tense and past participle of hyperphosphorylate.
  • hypocholesterolemia — an abnormally low amount of cholesterol in the blood.
  • hypolipoproteinemia — An abnormally low level of lipoprotein in the blood.
  • hysterosalpingogram — An X-ray image taken during hysterosalpingography.
  • imperative language — (language)   Any programming language that specifies explicit manipulation of the state of the computer system, not to be confused with a procedural language, which specifies an explicit sequence of steps to perform. An example of an imperative (but non-procedural) language is a data manipulation language for a relational database management system. This specifies changes to the database but does not necessarily require anyone to specify a sequence of steps. Both contrast with declarative languages, which specify neither explicit state manipulation nor a sequence of steps.
  • impressionistically — In an impressionistic manner.
  • in particular terms — If you say something in particular terms, you say it using a particular type or level of language or using language which clearly shows your attitude.
