Connection to “Taxi” (the Vehicle): 「タクシー」(車両)との関連性:
The word “taxi” is short for “taxicab,” which itself is derived from “taximeter cab.” The term “taximeter” comes from the French word taximètre, which is based on the Latin word taxare, meaning “to assess or estimate.” Just like a taxi (the vehicle) moves people short distances for a fee, the idea of “taxiing” in aviation refers to the airplane moving a short distance on the ground, typically from the gate to the runway or vice versa.
The term “taxiing” was adopted in aviation in the early 20th century to describe the process of an aircraft moving on the ground under its own power, but not yet flying. The comparison comes from the similarity between a taxi taking passengers from one place to another and an aircraft moving on the ground to get into position for takeoff or after landing.
Tax (the noun, as in money paid to the government) and tax (the verb, meaning to impose a burden) both derive from the Latin word “taxare”, which means “to assess” or “to estimate.” From “taxare”, we get the idea of assessing or imposing a charge (leading to the modern financial term “tax”).The verb “to tax” also evolved to mean “to put a burden on” or “to strain,” which led to the adjective “taxing”.
