airliner

the word 'airliner' is a modern compound formed from three distinct elements. the first part, 'air', originates from greek aēr, referring to the lower atmosphere, and entered english via latin and french. the second element, 'line', derives from latin linea meaning "linen thread" or "course", evolving to signify a regular route of travel. the agent suffix '-er', of germanic origin, is used to form nouns denoting things associated with an action. thus, the literal construction "that which performs an air line" logically evolved in the early 20th century to specifically designate a large aircraft operating on a scheduled passenger route.
