  • golden samphire — a Eurasian coastal plant, Inula crithmoides, with fleshy leaves and yellow flower heads: family Asteraceae (composites)
  • golden starfish — an award given to a bathing beach that meets EU standards of cleanliness
  • goodheartedness — The quality of being goodhearted.
  • gramophonically — in a gramophonic manner
  • grandparenthood — The state of being a grandparent.
  • graph colouring — (application)   A constraint-satisfaction problem often used as a test case in research, which also turns out to be equivalent to certain real-world problems (e.g. register allocation). Given a connected graph and a fixed number of colours, the problem is to assign a colour to each node, subject to the constraint that any two connected nodes cannot be assigned the same colour. This is an example of an NP-complete problem. See also four colour map theorem.
  • graph reduction — A technique invented by Chris Wadsworth where an expression is represented as a directed graph (usually drawn as an inverted tree). Each node represents a function call and its subtrees represent the arguments to that function. Subtrees are replaced by the expansion or value of the expression they represent. This is repeated until the tree has been reduced to a value with no more function calls (a normal form). In contrast to string reduction, graph reduction has the advantage that common subexpressions are represented as pointers to a single instance of the expression which is only reduced once. It is the most commonly used technique for implementing lazy evaluation.
  • greenham common — a village in West Berkshire unitary authority, Berkshire; site of a US cruise missile base, and, from 1981, a camp of women protesters against nuclear weapons; although the base had closed by 1991 a small number of women remained until 2000
  • gregorian chant — the plain song or cantus firmus used in the ritual of the Roman Catholic Church.
  • grind to a halt — If a country's economy or something such as a process grinds to a halt, it gradually becomes slower or less active until it stops.
  • guard of honour — A guard of honour is an official parade of troops, usually to celebrate or honour a special occasion, such as the visit of a head of state.
  • gynandromorphic — (of an organism) Having male and female characteristics.
  • hacking x for y — [ITS] Ritual phrasing of part of the information which ITS made publicly available about each user. This information (the INQUIR record) was a sort of form in which the user could fill out various fields. On display, two of these fields were always combined into a project description of the form "Hacking X for Y" (e.g. ""Hacking perceptrons for Minsky""). This form of description became traditional and has since been carried over to other systems with more general facilities for self-advertisement (such as Unix plan files).
  • haemoglobinuria — the presence of haemoglobin in the urine
  • haemoglobinuric — relating to the presence of haemoglobin in the urine
  • hair extensions — synthetic or human hair attached to the hair on someone's head to give the appearance of longer hair
  • half-round file — a file having a semicircular cross-section
  • half-understood — partially understood
  • halting problem — The problem of determining in advance whether a particular program or algorithm will terminate or run forever. The halting problem is the canonical example of a provably unsolvable problem. Obviously any attempt to answer the question by actually executing the algorithm or simulating each step of its execution will only give an answer if the algorithm under consideration does terminate, otherwise the algorithm attempting to answer the question will itself run forever. Some special cases of the halting problem are partially solvable given sufficient resources. For example, if it is possible to record the complete state of the execution of the algorithm at each step and the current state is ever identical to some previous state then the algorithm is in a loop. This might require an arbitrary amount of storage however. Alternatively, if there are at most N possible different states then the algorithm can run for at most N steps without looping. A program analysis called termination analysis attempts to answer this question for limited kinds of input algorithm.
  • hamiltonstovare — a large strong short-haired breed of hound with a black, brown, and white coat
  • harbour station — the part of a port where boats shelter or station
  • hard of hearing — partially deaf
  • hardhead sponge — any of several commercial sponges, as Spongia officinalis dura, of the West Indies and Central America, having a harsh, fibrous, resilient skeleton.
  • hare and hounds — an outdoor game in which certain players, the hares, start off in advance on a long run, scattering small pieces of paper, called the scent, with the other players, the hounds, following the trail so marked in an effort to catch the hares before they reach a designated point.
  • harmonic motion — periodic motion consisting of one or more vibratory motions that are symmetric about a region of equilibrium, as the motion of a vibrating string of a musical instrument.
  • harmonic series — a series in which the reciprocals of the terms form an arithmetic progression.
  • haute-normandie — a region of NW France, on the English Channel: generally fertile and flat
  • have a crush on — be attracted to: sb
  • have a derry on — to have a prejudice or grudge against
  • have an eye for — the organ of sight, in vertebrates typically one of a pair of spherical bodies contained in an orbit of the skull and in humans appearing externally as a dense, white, curved membrane, or sclera, surrounding a circular, colored portion, or iris, that is covered by a clear, curved membrane, or cornea, and in the center of which is an opening, or pupil, through which light passes to the retina.
  • have no use for — to employ for some purpose; put into service; make use of: to use a knife.
  • hay conditioner — either of two machines, one designed to crush stems of hay, the other to break and bend them, in order to cause more rapid and even drying

  • heart condition — cardiac disorder
  • heart operation — a surgical operation performed on the heart
  • heart tamponade — tamponade (def 2).
  • heart's content — Anatomy. a hollow, pumplike organ of blood circulation, composed mainly of rhythmically contractile smooth muscle, located in the chest between the lungs and slightly to the left and consisting of four chambers: a right atrium that receives blood returning from the body via the superior and inferior vena cavae, a right ventricle that pumps the blood through the pulmonary artery to the lungs for oxygenation, a left atrium that receives the oxygenated blood via the pulmonary veins and passes it through the mitral valve, and a left ventricle that pumps the oxygenated blood, via the aorta, throughout the body.
  • heartbrokenness — The state or quality of being heartbroken.
  • hearth and home — domestic realm
  • hemadynamometer — An instrument by which the pressure of the blood in the arteries, or veins, is measured by the height to which it will raise a column of mercury.
