The Latin term for a temporary doctor is "locum tenens", which translates to "placeholder" or "substitute". This term is commonly used in the medical profession to refer to a physician who fills in for another physician on a temporary basis. The locum tenens is not a permanent staff member, but instead, provides relief coverage while the regular physician is away or unavailable. The practice of hiring a locum tenens is especially common in rural areas where there may be a shortage of physicians or in situations where a physician needs to take a leave of absence.
