Usage notesEdit

The most common use of this is in front of an adjective or adjectival phrase, to denote superlativity.

A 2007 decision by the Patent Court of Korea found that while the superlative sense of 제일 is not distinctive, the use of 제일 in front of a noun is distinctive and can be protected by trademark. [1]
