C The third letter in the Latin alphabet and its descendants corresponds in position and in origin to the Greek Gamma (Γ, γ), which in its turn is borrowed from the third symbol of the Phoenician alphabet (Heb. Gimel). The earliest Semitic records give its form as or more frequently or . The form is found in the earliest inscriptions of Crete, Attica, Naxos and some other of the Ionic islands. In Argolis and Euboea especially a form with legs of unequal length is found . From this it is easy to pass to the most widely spread Greek form, the ordinary . In Corinth, however, and its colony Corcyra, in Ozolian Locris and Elis, a form inclined at a different angle is found. From this form the transition is simple to the rounded , which is generally found in the same localities as the pointed form, but is more widely spread, occurring in Arcadia and on Chalcidian vases of the 6th century B.C., in Rhodes and Megara with their colonies in Sicily. In all these cases the sound represented was a hard G (as in gig). The rounded form was probably that taken over by the Romans and with the value of G. This is shown by the permanent abbreviation of the proper names Gaius and Gnaeus by C. and Cn. respectively. On the early inscription discovered in the Roman Forum in 1899 the letter occurs but once, in the form written from right to left. The broad lower end of the symbol is rather an accidental pit in the stone than an attempt at a diacritic mark—the word is regei, in all probability the early dative form of rex, “king.” It is hard to decide why Latin adopted the g-symbol with the value of k, a letter which it possessed originally but dropped, except in such stereotyped abbreviations as K. for the proper name Kaeso and Kal. for Calendae. There are at least two possibilities: (1) that in Latium g and k were pronounced almost identically, as, e.g., in the German of Württemberg or in the Celtic dialects, the difference consisting only in the greater energy with which the k-sound is produced; (2) that the confusion is graphic, K being sometimes written , which was then regarded as two separate symbols. A further peculiarity of the use of C in Latin is in the abbreviation for the district Subura in Roma and its adjective Suburanus, which appears as SVC. Here C no doubt represents G, but there is no interchange between g and b in Latin. In other dialects of Italy b is found representing an original voiced guttural (gw), which, however, is regularly replaced by v in Latin. As the district was full of traders, Subura may very well be an imported word, but the form with C must either go back to a period before the disappearance of g before v or must come from some other Italic dialect. The symbol G was a new coinage in the 3rd century B.C. The pronunciation of C throughout the period of classical Latin was that of an unvoiced guttural stop (k). In other dialects, however, it had been palatalized to a sibilant before i-sounds some time before the Christian era; e.g. in the Umbrian façia = Latin facial. In Latin there is no evidence for the interchange of c with a sibilant earlier than the 6th century A.D. in south Italy and the 7th century A.D. in Gaul (Lindsay, Latin Language, p. 88). This change has, however, taken place in all Romance languages except Sardinian. In Anglo-Saxon c was adopted to represent the hard stop. After the Norman conquest many English words were re-spelt under Norman influence. Thus Norman-French spelt its palatalized c-sound (=tsh) with ch as in cher and the English palatalized cild, &c. became child, &c. In Provençal from the 10th century, and in the northern dialects of France from the 13th century, this palatalized c (in different districts ts and tsh) became a simple s. English also adopted the value of s for c in the 13th century before e, i and y. In some foreign words like cicala the ch- (tsh) value is given to c. In the transliteration of foreign languages also it receives different values, having that of tsh in the transliteration of Sanskrit and of ts in various Slavonic dialects.

As a numeral C denotes 100. This use is borrowed from Latin, in which the symbol was originally , a form of the Greek θ. This, like the numeral symbols later identified with L and M, was thus utilized since it was not required as a letter, there being no sound in Latin corresponding to the Greek θ. Popular etymology identified the symbol with the initial letter of centum, “hundred.”  (P. Gi.) 

CAB (shortened about 1825 from the Fr. cabriolet, derived from cabriole, implying a bounding motion), a form of horsed vehicle for passengers either with two (“hansom”) or four wheels (“four-wheeler” or “growler”), introduced into London as the cabriolet de place, from Paris in 1820 (see Carriage). Other vehicles plying for hire and driven by mechanical means are included in the definition of the word “cab” in the London Cab and Stage Carriage Act 1007. The term “cab” is also applied to the driver’s or stoker’s shelter on a locomotive-engine.

Cabs, or hackney carriages, as they are called in English acts of parliament, are regulated in the United Kingdom by a variety of statutes. In London the principal acts are the Hackney Carriage Acts of 1831-1853, the Metropolitan Public Carriages Act 1869, the London Cab Act 1896 and the London Cab and Stage Carriage Act 1907. In other large British towns cabs are usually regulated by private acts which incorporate the Town Police Clauses Act 1847, an act which contains provisions more or less similar to the London acts. The act of 1869 defined a hackney carriage as any carriage for the conveyance of passengers which plies for hire within the metropolitan police district and is not a stage coach, i.e. a conveyance in which the passengers are charged separate and distinct fares for their seats. Every cab must be licensed by a licence renewable every year by the home secretary, the licence being issued by the commissioner of police. Every cab before being licensed must be inspected at the police station of the district by the inspector of public carriages, and certified by him to be in a fit condition for public use. The licence costs £2. The number of persons which the cab is licensed to carry must be painted at the back on the outside. It must carry a lighted lamp during the period between one hour after sunset and one hour before sunrise. The cab must be under the charge of a driver having a licence from the home secretary. A driver before obtaining a licence, which costs five shillings per annum, must pass an examination as to his ability to drive and as to his knowledge of the topography of London.

General regulations with regard to fares and hiring may be made from time to time by the home secretary under the London Cab and Stage Carriage Act 1907. The hiring is by distance or by time as the hirer may decide at the beginning of the hiring; if not otherwise expressed the fare is paid according to distance. If a driver is hired by distance he is not compelled to drive more than six miles, and if hired by time he is not compelled to drive for more than one hour. When a cab is hired in London by distance, and discharged within a circle the radius of which is four miles (the centre being taken at Charing Cross), the fare is one shilling for any distance not exceeding two miles, and sixpence for every additional mile or part of a mile. Outside the circle the fare for each mile, or part of a mile, is one shilling. When a cab is hired by time, the fare (inside or outside the circle) is two shillings and sixpence for the first hour, and eightpence for every quarter of an hour afterwards. Extra payment has to be made for luggage (twopence per piece outside), for extra passengers (sixpence each for more than two), and for waiting (eightpence each completed quarter of an hour). If a horse cab is fitted with a taximeter (vide infra) the fare for a journey wholly within or partly without and partly within the four-mile radius, and not exceeding one mile or a period of ten minutes, is sixpence. For each half mile or six minutes an additional threepence is paid. If the journey is wholly without the four-mile radius the fare for the first mile is one shilling, and for each additional quarter of a mile or period of three minutes, threepence is paid. If the cab is one propelled by mechanical means the fare for a journey not
