개요
'~기로 하다'는 동사 뒤에 붙어 주어의 결심이나 타인과의 약속을 나타내는 문법입니다. 주로 이미 결정된 사실을 전달하거나, 앞으로 할 일을 다짐할 때 사용합니다. 2) 사용 패턴: 동사 어간 뒤에 '-기로 하다'를 붙입니다. 받침 유무와 관계없이 동일하게 사용하며, 과거형인 '~기로 했다'를 쓰면 이미 결정된 일을 의미합니다. 3) 공통 문맥: 친구와의 약속, 계획 세우기, 다이어트나 공부 같은 개인적인 결심 등 일상적인 상황에서 매우 빈번하게 사용됩니다. 4) 유의어 비교: '~기로 했다'와 '~기로 마음먹었다'는 의미가 비슷하지만, '~기로 했다'는 약속의 의미가 강하고 '~기로 마음먹었다'는 개인적인 의지가 더 강조됩니다.
