Mandaic As and Hebrew Samekh occupy the same place in the twenty-two letter Aramaic sequence. Hebrew keeps the inherited noun as the letter name and the numeral value 60; Mandaic keeps neither. Where the Mandaic shapes came from is disputed, a cursive Aramaic hand or the Parthian chancery script.

Both signs continue the same Northwest Semitic consonant inherited from a shared abjad ancestor; this is a cognate correspondence, not a borrowing in either direction. Ugaritic and Hebrew share the same twenty-two-consonant core, with Ugaritic adding six further signs Hebrew never developed separately.

Why this is disputed. Sat and the Hebrew samekh cover the plain s of the family, but the reduction that produced each letter was not the same reduction. Both descend from the same Proto Sinaitic sign, but comparative Semitists differ on whether the Ge'ez and Hebrew forms split before or after the broader Semitic sibilant mergers, so the letters' shared function does not settle how closely related their actual histories are.

Syriac Semkath and Hebrew Samekh stand at the same place in the twenty-two letter Aramaic sequence and carry the same letter-numeral value, 60. The Syriac script grew out of the local Aramaic cursive of Edessa and the Hebrew square script out of the same Aramaic alphabet, so the two letters are inherited from one ancestor rather than borrowed from each other.

Cognate letters. Arabic sin and Hebrew samekh both continue the twenty-two letter Northwest Semitic alphabet, and they hold the same place in the inherited order and the same numeral value, 60. Neither is derived from the other.

Samaritan Singaat and Hebrew Samekh are cognates at the value 60. The names have drifted further apart here than anywhere else in the sequence, which is a reminder that letter names travelled with the script and were reshaped by the people using it, while the position and the numeral value did not move.

Greek Xi and Hebrew Samekh are cognates. Both continue the same Phoenician sign, which is why both carry the numeral value 60 in their letter-number systems. A shared ancestor, not a borrowing in either direction. The Greek alphabet was adapted from the Phoenician abjad in the early first millennium BC, and the Hebrew square script descends from the same abjad through Aramaic.
