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 𐌲 g, called giba. The same rune also appears in the Elder Futhark, with a suggested Proto-Germanic name *gebô "gift". J. H. Looijenga speculates that the rune is directly derived from Latin Χ, the pronunciation of which may have been similar to Germanic gs in the 1st century, e.g., Gothic reihs compared to Latin rex (as opposed to the Etruscan alphabet, where /𐌗 had a value of [s]).
The gyfu rune is sometimes used as a symbol within modern mysticism, particularly amongst those interested in Celtic mythology. It's described, for example, in the book The Runic Tarot as a representation of the giving-receiving balance in friendships.
Sitting in a dark room
Falling to pieces
Try to find the right words
So you can sing along
Wear it like a tight noose
I don't wanna feel this
Might of made a wrong move
Now I'm all alone
I never know which way to go
A million thoughts I can't control
The city sleeps, but I can't close my eyes
California
California
Drowning in a bright room
Faking the feelings
Wonder if the right words
Are even here at all
I'm living through the hardest part
In a city full of fallen stars
A million dreams I can't close my eyes
California
California
