臺

Ideogram:

Formed from 高 (고, “high”) + 至 (지, “to arrive”);

Symbolizes a high platform that has been reached.

Used as a counter for vehicles in Korean (e.g., 승용차 100대 = “100 cars”).

Functions as a suffix to indicate approximate quantities (e.g., 100억대의 자산가 = “a billionaire worth around 10 billion won”).

In modern writing, 台 often replaces 臺 in China, Japan, and even Taiwan, but technically the two are not identical.

In Korean, care is needed because 台 is also read as 태, leading to frequent misreadings when it substitutes for 臺.
