Cross-like marks and graphemes[edit]

Further information: X mark

The cross mark is used to mark a position, or as a check mark, but also to mark deletion. Derived from Greek Chi are the Latin letter X, Cyrillic Kha and possibly runic Gyfu.
Egyptian hieroglyphs involving cross shapes include ankh "life", ndj "protect" and nfr "good; pleasant, beautiful".
Sumerian cuneiform had a simple cross-shaped character, consisting of a horizontal and a vertical wedge (𒈦), read as maš "tax, yield, interest"; the superposition of two diagonal wedges results in a decussate cross (𒉽), read as pap "first, pre-eminent" (the superposition of these two types of crosses results in the eight-pointed star used as the sign for "sky" or "deity" (𒀭), DINGIR). The cuneiform script has other, more complex, cruciform characters, consisting of an arrangement of boxes or the fourfold arrangement of other characters, including the archaic cuneiform characters LAK-210, LAK-276, LAK-278, LAK-617 and the classical sign EZEN (𒂡).^[15]
Phoenician tāw is still cross-shaped in Paleo-Hebrew alphabet and in some Old Italic scripts (Raetic and Lepontic), and its descendant T becomes again cross-shaped in the Latin minuscule t. The plus sign (+) is derived from Latin t via a simplification of a ligature for et "and" (introduced by Johannes Widmann in the late 15th century).
The letter Aleph is cross-shaped in Aramaic and paleo-Hebrew.
Egyptian hieroglyphs with cross-shapes include Gardiner Z9 – Z11 ("crossed sticks", "crossed planks").
Other, unrelated cross-shaped letters include Brahmi ka (predecessor of the Devanagari letter क) and Old Turkic (Orkhon) d² and Old Hungarian b, and Katakana ナ na and メme.
The multiplication sign (×), often attributed to William Oughtred (who first used it in an appendix to the 1618 edition of John Napier's Descriptio) apparently had been in occasional use since the mid 16th century.^[16]
Other typographical symbols resembling crosses include the dagger or obelus (†), the Chinese (十, Kangxi radical 24) and Roman (X) ten.
Unicode has a variety of cross symbols in the "Dingbat" block (U+2700–U+27BF) :

✕ ✖ ✗ ✘ ✙ ✚ ✛ ✜ ✝ ✞ ✟ ✠ ✢ ✣ ✤ ✥

The Miscellaneous Symbols block (U+2626 to U+262F) adds three specific Christian cross variants, viz. the Patriarchal cross (☦), Cross of Lorraine (☨) and "Cross of Jerusalem" (implemented as Cross potent, ☩).
