Aerate means “to send air”, and the etymology comes from aer (air).
Aerate means sending air into the water or the soil. The similar meaning word “ventilate” is used for buildings and rooms. Let’s see an example sentence.
Looking at the aqua shop’s aquarium, bubbles are rising from the bottom. This is because it aerates the inside of the aquarium and supplies oxygen. Aeration is also carried out at the water purification treatment facility to send oxygen to microorganisms.
Aeration is also done on earth. Breathability and drainage are enhanced by piercing the lawn and aerating the soil.
Aerial means “from aircraft”, and the etymology comes from aer (air). Let’s see an example sentence.
Aerial attack means to do bombs from air or sweep machine guns with aircraft. Its synonyms are airstrike and air-raid. Aerial photographs were used for reconnaissance in the past, but now they are used to create topographic maps.
Aerial navigator is the national qualifications required to measure aircraft current position and its course. A certain flight career is necessary to obtain the qualification of the aerial navigator.
Aerobic means “using oxygen”, and the etymology comes from aero (oxygen) and bio (bio). The antonym is anaerobic.
Aerobic means that creatures use oxygen by exercise and life activities. Let’s see an example sentence.
Aerobic exercise consumes fat and carbohydrates in the body with oxygen. Jogging, swimming, cycling and other long-running exercises are classified as aerobic exercise.
Aerobic exercise has the effect of burning fat, making it ideal for weight loss. Other benefits of aerobic exercise are improved cardiopulmonary function, reduced risk of depression, activation of memory cells in the brain.
Aerobic is also used in the field of biology. Aerobic organisms are those that metabolize with oxygen. Most animals are classified as aerobic organisms.
Aerobics means “an exercise using music and dance”, and the etymology comes from aerobic (aerobic). This word makes a singular form.
Aerobics is an aerobic exercise performed according to music. It is usually done with the instructor accompanied by the class.
The biggest advantage of aerobics is easy continuation. Normal exercise is monotonous and boring, but anyone can enjoy aerobics casually. For those who dislike exercise, we will recommend aerobics by all means.
Aerospace means “industry of airplane or space vehicles”, and the origin is derived from aero (air) and space (universe).
Aerospace is an academic field that makes spacecraft and aircraft. Let’s see an example sentence.
The aerospace industry are developing aircraft, spacecraft, guided missiles and propulsion devices, artificial satellites, and so on. In most developed countries, public institutions cooperate with the private industry to form the aerospace industry. As a result, aerospace companies will take orders from the government for most jobs.
Aerodynamics means “study of air movement”, and the origin is derived from aero (air) and dynamis (power). Aerodynamics is a study for the motion of air and the movement of objects in the air. Let’s see an example sentence.
If the object moves in the air, it always receives air resistance. Therefore, in order to move the object efficiently, it is necessary to investigate the motion of the air.
Aerodynamics is used in the development of transportation vehicles such as automobiles, aircraft and railroads. Aerodynamics makes it possible to develop vehicles with low air resistance.
Airline means “transportation business by airplane”, and the origin is derived from air and line. The original meaning is “the aerial line connecting two points on the earth”.
Airline means a company that carries passengers and cargo using aircraft. Let’s see an example sentence.
The airline owns passenger aircraft and obtains profits by transporting passengers and cargo. There are two major types of airline companies, LCC and Legacy carrier.
LCC (Low Cost Carrier) is cheap, but service is simplified. Legacy carriers offer high quality fares and frequent flyer services, although fares are high. (Mileage service is Japanese English)
Anaerobic means “not using oxygen” , and the origin is derived from an (not) and aerobic (aerobic). Anaerobic means not using oxygen in exercise or metabolism. Let’s see an example sentence.
Anaerobic exercise is exercise that does not use oxygen for energy consumption such as muscle training or sprint. If you train your muscles with anaerobic exercise, you can increase basal metabolism, though slightly.
Anaerobic is also used in biology. Anaerobic organisms are organisms that do not use oxygen for metabolism, and are used for sewage treatment.
