The word "voke" is a shortened form of the word "invoke", which comes from the Latin word "invocare". "Invocare" is derived from the prefix "in-" meaning "in" or "upon", and "vocare" meaning "to call". Thus, "invoke" originally meant "to call upon" or "to appeal to". Over time, "voke" emerged as a colloquial abbreviation of "invoke" that is sometimes used informally.
