Gyfu is the name for the g-rune ᚷ in the Anglo-Saxon rune poem, meaning "gift" or "generosity":
The corresponding letter of the Gothic alphabet is Ќ g, called giba. The same rune is also appears in the Elder Futhark, with a suggested Proto-Germanic name *geb҃ "gift". J. H. Looijenga speculates that the rune is directly derived from Latin Ԏ, the pronunciation of which may have been similar to Germanic gs in the 1st century, eg. Gothic reihs compared to Latin rex (as opposed to the Etruscan alphabet, where /ǰЌ had a value of [s]).
