The letter G is the seventh letter and fifth consonant of our alphabet, and evolves from the Phoenician gimel and the Greek gamma. G is a guttural consonant, articulated in the back of the mouth or throat. It can sound hard (a velar plosive, where the back of the tongue comes in contact with the soft palate)—guard, Garamond, guts, glue; or soft (a velar nasal)—sing, gin, danger, ginger; or even silent!—gnat, gnome, design, diaphragm. The lowercase g is typographically rich, with single-storey and double-storey variants, bowls, ears, loops, tails and ears.
