Slay
A nickname surname from Old English and Middle English words meaning “sly” or “crafty,” though some families may also reflect the loom term “slay.”
The #8,135 most common surname in the United States (2010 Census) — about 1 in every 75,766 Americans shares it.
Etymology
In the main English surname tradition, Slay is treated as a nickname form related to Middle English sly and older words meaning “crafty” or “cunning.” Harrison specifically gives it as a variant of Sly, linking it to Middle English and Old Norse forms with that sense. Some 19th-century writers also noticed the separate word slay meaning a weaver’s reed or shuttle part, but that explanation is mainly relevant to occupational surnames like Slaymaker or Slayman rather than to Slay itself.
History
The surname appears in English records as a short nickname-type name and is one of several spellings clustered around Sly. In surname dictionaries of the 19th century it is listed alongside occupational forms such as Slaymaker and Slayman, showing how closely the words could be confused in spelling and interpretation. Modern bearers in the United States likely descend from more than one small English line, with no single origin sufficient for every family.

Fun fact
The same old word family that can underlie Slay also produced surname forms linked to a weaver’s tool, the “slay,” used in weaving looms.
