Sic

Sic is a Latin word meaning "thus", "so", "as such", or "in such a manner". In writing, it is placed within the quoted material, in square brackets – or outside it, in regular parentheses – and usually italicized – [sic] – to indicate that an incorrect or unusual spelling, phrase, punctuation, and/or other preceding quoted material has been reproduced verbatim from the quoted original and is not a transcription error.

It had a long vowel in Latin (sīc), meaning that it was pronounced like the English word "seek" (IPA /'sik/); however, it is normally anglicised to /'sɪk/ (like the English word "sick").
