G (named gee /dʒiː/) is the 7th letter in the ISO basic Latin alphabet.
The letter 'G' was introduced in the Old Latin period as a variant of 'C' to distinguish voiced /ɡ/ from voiceless /k/. The recorded originator of 'G' is freedman Spurius Carvilius Ruga, the first Roman to open a fee-paying school, who taught around 230 BC. At this time, 'K' had fallen out of favor, and 'C', which had formerly represented both /ɡ/ and /k/ before open vowels, had come to express /k/ in all environments.
Ruga's positioning of 'G' shows that alphabetic order related to the letters' values as Greek numerals was a concern even in the 3rd century BC. According to some records, the original seventh letter, 'Z', had been purged from the Latin alphabet somewhat earlier in the 3rd century BC by the Roman censor Appius Claudius, who found it distasteful and foreign. Sampson (1985) suggests that: "Evidently the order of the alphabet was felt to be such a concrete thing that a new letter could be added in the middle only if a 'space' was created by the dropping of an old letter."
George Hempl (1899) proposes that there never was such a "space" in the alphabet and that in fact 'G' was a direct descendant of zeta. Zeta took shapes like ⊏ in some of the Old Italic scripts; the development of the monumental form 'G' from this shape would be exactly parallel to the development of 'C' from gamma. He suggests that the pronunciation /k/ > /ɡ/ was due to contamination from the also similar-looking 'K'.
Eventually, both velar consonants /k/ and /ɡ/ developed palatalized allophones before front vowels; consequently in today's Romance languages, ⟨c⟩ and ⟨g⟩ have different sound values depending on context (known as hard and soft C and hard and soft G). Because of French influence, English orthography shares this feature.
The modern lowercase 'g' has two typographic variants: the single-story (sometimes opentail) '' and the double-story (sometimes looptail) ''. The single-story form derives from the majuscule (uppercase) form by raising the serif that distinguishes it from 'c' to the top of the loop, thus closing the loop, and extending the vertical stroke downward and to the left. The double-story form (g) had developed similarly, except that some ornate forms then extended the tail back to the right, and to the left again, forming a closed bowl or loop. The initial extension to the left was absorbed into the upper closed bowl. The double-story version became popular when printing switched to "Roman type" because the tail was effectively shorter, making it possible to put more lines on a page. In the double-story version, a small top stroke in the upper-right, often terminating in an orb shape, is called an "ear".
Generally, the two forms are complementary, but occasionally the difference has been exploited to provide contrast. The 1949 Principles of the International Phonetic Association recommends using for advanced voiced velar plosives (denoted by Latin small letter script G) and for regular ones where the two are contrasted, but this suggestion was never accepted by phoneticians in general, and today '' is the symbol used in the International Phonetic Alphabet, with '' acknowledged as an acceptable variant and more often used in printed materials.
Use in writing systems
In English, the letter appears either alone or in some digraphs. Alone, it represents
In words of Romance origin, ⟨g⟩ is mainly soft before ⟨e⟩ (including the digraphs ⟨ae⟩ and ⟨oe⟩), ⟨i⟩, or ⟨y⟩, and hard otherwise. There are many English words of non-Romance origin where ⟨g⟩ is hard though followed by ⟨e⟩ or ⟨i⟩ (e.g. get, gift), and a few in which ⟨g⟩ is soft though followed by ⟨a⟩ such as gaol or margarine.
The double consonant ⟨gg⟩ has the value /ɡ/ (hard ⟨g⟩) as in nugget, with very few exceptions: /ɡd͡ʒ/ in suggest and /d͡ʒ/ in exaggerate and veggies.
The digraph ⟨dg⟩ has the value /d͡ʒ/ (soft ⟨g⟩), as in badger. Non-digraph ⟨dg⟩ can also occur, in compounds like floodgate and headgear.
The digraph ⟨ng⟩ may represent
Non-digraph ⟨ng⟩ also occurs, with possible values
The digraph ⟨gh⟩ (in many cases a replacement for the obsolete letter yogh, which took various values including /ɡ/, /ɣ/, /x/ and /j/) may represent
Non-digraph ⟨gh⟩ also occurs, in compounds like foghorn, pigheaded
The digraph ⟨gn⟩ may represent
Non-digraph ⟨gn⟩ also occurs, as in signature, agnostic
The trigraph ⟨ngh⟩ has the value /ŋ/ as in gingham or dinghy. Non-trigraph ⟨ngh⟩ also occurs, in compounds like stronghold and dunghill.
Most Romance languages and some Nordic languages also have two main pronunciations for ⟨g⟩, hard and soft. While the soft value of ⟨g⟩ varies in different Romance languages (/ʒ/ in French and Portuguese, in Catalan, /d͡ʒ/ in Italian and Romanian, and /x/ in most dialects of Spanish), in all except Romanian and Italian, soft ⟨g⟩ has the same pronunciation as the ⟨j⟩.
In Italian and Romanian, ⟨gh⟩ is used to represent /ɡ/ before front vowels where ⟨g⟩ would otherwise represent a soft value. In Italian and French, ⟨gn⟩ is used to represent the palatal nasal /ɲ/, a sound somewhat similar to the ⟨ny⟩ in English canyon. In Italian, the trigraph ⟨gli⟩, when appearing before a vowel or as the article and pronoun gli, represents the palatal lateral approximant /ʎ/.
Other languages typically use ⟨g⟩ to represent /ɡ/ regardless of position.
Amongst European languages Czech, Dutch and Finnish are an exception as they do not have /ɡ/ in their native words. In Dutch ⟨g⟩ represents a voiced velar fricative /ɣ/ instead, a sound that does not occur in modern English, but there is a dialectal variation: many Netherlandic dialects use a voiceless fricative ( or ) instead, and in southern dialects it may be palatal . Nevertheless, word-finally it is always voiceless in all dialects, including the standard Dutch of Belgium and the Netherlands. On the other hand, some dialects (like Amelands), may have a phonemic /ɡ/.
Faroese uses ⟨g⟩ to represent /dʒ/, in addition to /ɡ/, and also uses it to indicate a glide.
In Maori (Te Reo Māori), ⟨g⟩ is used in the digraph ⟨ng⟩ which represents the velar nasal /ŋ/ and is pronounced like the ⟨ng⟩ in singer.
In older Czech and Slovak orthographies, ⟨g⟩ was used to represent /j/, while /ɡ/ was written as ⟨ǧ⟩ (⟨g⟩ with caron).
