* 똑똑하다 (ttok-ttok-hada): This is a common and versatile word meaning "smart," "intelligent," or "bright." It's a good general choice for "clever" if you mean intellectually quick-witted.
* 영리하다 (yeong-ri-hada): This word emphasizes shrewdness and resourcefulness. It suggests cleverness in a practical, perhaps even cunning, way.
* 기발하다 (gi-bal-hada): This means "ingenious" or "inventive." It's suitable when describing someone who is clever at coming up with creative solutions or ideas.
* 재치 있다 (jae-chi itda): This translates to "have wit" or "be witty." This is a good choice if you're referring to someone who is clever with words or humor.
The best word to use will depend on the context. For example:
* "He's a clever boy." Could be: 그는 똑똑한 남자예요 (geuneun ttok-ttok-han namjayeoyo)
* "She's clever with her finances." Could be: 그녀는 영리하게 재정을 관리해요 (geunyeoneun yeong-ri-hage jaejeng-eul gwan-lihaeyo)
* "That's a clever solution!" Could be: 그건 기발한 해결책이에요! (geugeon gi-bal-han haegyeolchaek-ieyo!)
Consider the specific situation and choose the word that best fits the nuance of "clever" you want to express.
