Register and Politeness
'공식' is a neutral noun and can be used in both formal and informal contexts depending on the sentence. It is often found in formal or written language but is also common in spoken Korean when discussing official matters.
Common Mistakes
Learners sometimes confuse '공식' with '공식적' (the adjective meaning 'official'). Remember that '공식' is a noun meaning 'formula' or 'official thing', while '공식적' is the adjective form used to describe something as official.
Use '공식' when referring to the noun itself, and '공식적' when modifying other nouns.
