Etymology : Vocation has been making its voice heard in English since the 15th century, when it referred to a summons from God to perform a particular task or function in life, especially a religious career. It should come as no surprise, then, that the word is a descendant of Latin vocatio, meaning “summons.” Vocatio, in turn, comes from vocare, meaning “to call,” which itself is from vox, meaning “voice.” Vocation also has a secular position in the English language as a word for the strong desire to do a certain kind of work or the work itself, much like the words calling or occupation.
