Courier

Courier (Lat. currcre, to run), literally a runner or messenger. In this sense the messengers of the Foreign Office who take dispatches and the like to a foreign court or to representatives abroad are called couriers; but the name is more generally used to denote skilled attendants employed by travellers to lessen the embarrassment of travel by their knowledge of the language of the countries travelled through, and by their experience of the measures necessary for the travellers' comfort.
