Etymology: "Sid" in the sense of a cheating game player is a clipped form of "sidiki" or "sidiqi," a term from Persian-influenced Urdu and Hindi slang for a cardsharp or swindler. The full word is what gave the English-language shortening its meaning, and the clipped version is the one that has traveled furthest. Because the source only offers the shortening, the rest of the story is best told simply: the word belongs to the vocabulary of gambling and street hustling, where a skilled cheat was a familiar figure, and "sid" is the compressed version of that older term.

Synonyms: side, edge, flank, border, margin
