An aerodrome or airdrome is a location from which aircraft flight operations take place, regardless of whether they involve cargo, passengers, or neither. Aerodromes include small general aviation airfields, large commercial airports, and military airbases. The term airport may imply a certain stature (having satisfied certain certification criteria or regulatory requirements) that an aerodrome may not have achieved. That is to say, all airports are aerodromes, but not all aerodromes are airports. Usage of the term 'aerodrome' remains more common in the UK and Commonwealth nations, and is conversely almost unknown in American English.
According to the International Civil Aviation Organization (ICAO) an aerodrome is "A defined area on land or water (including any buildings, installations, and equipment) intended to be used either wholly or in part for the arrival, departure, and surface movement of aircraft."

The word aerodrome is derived from the Greek words aeras (αέρας), "air" and dromos (δρόμος), "road" or "course", literally meaning "air course".
In the UK, the term was used by the Royal Flying Corps in the First World War and Royal Air Force in the two World Wars as it had the advantage that their French allies, on whose soil they were based and with whom they co-operated, used the equivalent term (aérodrome).
The term aerodrome is used in International Civil Aviation Organization (ICAO) documents, for example in the Annex to the ICAO Convention about aerodromes, their physical characteristics, and their operation. However, the term airfield or airport has mostly superseded use of aerodrome after World War II.
History of aerodromes
In the early days of aviation, when there were no paved runways and all landing fields were grass, a typical airfield might permit takeoffs and landings in only a couple of directions, much like today's airports, whereas an aerodrome was distinguished, by virtue of its much greater size, by its ability to handle landings and take offs in any direction. The ability to always take off and land directly into the wind, regardless of the wind's direction, was an important advantage in the earliest days of aviation when an airplane's performance in a crosswind takeoff or landing might be poor or even dangerous. The development of differential braking in aircraft, the improved aircraft performance, the utilization of paved runways, and the fact that a circular aerodrome required much more space than did the "L" or triangle shaped airfield eventually made the early aerodromes obsolete.
The unimproved airfield remains a phenomenon in military aspects. The DHC-4 Caribou served in the U.S. military in Vietnam (designated as the CV-2), landing on rough, unimproved airfields where the C-130 workhorse could not operate. Earlier, the Ju-52 and Fieseler Storch could do the same, one example of the latter taking off from the Fuhrerbunker whilst completely surrounded by Russian troops.

Aerodromes by country
The Canadian Aeronautical Information Manual (AIM) says "...for the most part, all of Canada can be an aerodrome", however there are also "registered aerodromes" and "certified airports". To become a registered aerodrome the operator must maintain certain standards and keep the Minister of Transport (Canada) informed of any changes. To be certified as an airport the aerodrome, which usually supports commercial operations, must meet safety standards. Nav Canada, the private company responsible for air traffic control services in Canada, publishes the Canadian Flight Supplement (CFS), a directory of all registered Canadian land aerodromes, as well as the Water Aerodrome Supplement (WAS).
