Cuneiform TI or TÌL (Borger 2003 nr. ; U+122FE ?) has the main meaning of "life" when used ideographically. The written sign developed from the drawing of an arrow, since the words meaning "arrow" and "life" were pronounced similarly in the Sumerian language.
With the determinative UZU ? "flesh, meat", UZUTI, it means "rib". This homophony is exploited in the myth of Ninti ( NIN.TI "lady of life" or "lady of the rib"), created by Ninhursag to cure the ailing Enki. Since Eve is called "mother of life" in Genesis, together with her being taken from Adam's tsela` "side, rib", the story of Adam and Eve has sometimes been considered to derive from that of Ninti.
In Akkadian orthography, the sign has the syllabic values di or ?i, in Hittite ti, di or te.
The twelve tablet (I-XII) Epic of Gilgamesh uses the ti sign as follows (Parpola): ti (387 times), and TI (the sumerogram), (2 times). In the Epic, sumerogram TI is used for the Akkadian language word "balu", for "life; to live", as "TI.LA", in one location, Tablet XI 174, (and replacement in two locations, also as TI.LA in Tablets X, and XI).
