G is the seventh letter in the Roman alphabet.

History

The letter G was created by the Romans because they felt that C was not an adequate letter to represent both /k/ and /g/. Fascinatingly, the alleged inventor is a known historical figure, Spurius Carvilius Ruga (who flourished around 230 BC). G, which at this time took the place of the letter Z, came to represent the sound /g/. As the sound /k/ did, /g/ also developed palatal and velar allophones which is why today, G has different sound values in all Romance languages and English (due to French influence).

Usage

In English, the letter can be pronounced as a "soft G" (SAMPA: [dZ]), as in: giant, ginger, geology, or it can be pronounced as a "hard G" (SAMPA: [g]), as in: goose, gargoyle, game.

In Spanish, -ge- and -gi- are pronounced as -je- and -ji-. The Spanish poet Juan Ramón Jiménez proposed to simplify the Spanish spelling by using just the versions with j. Thus, while the rest of Spanish speakers didn't follow him, his works and the translations of Rabindranath Tagore made by Jiménez's wife Zenobia Camprubí are published in his spelling.
