“단어 기억이 안 나 이게 뭐더라” 나이를 먹어서 그런건지, 젊은 치매인건지, 건망증인지 걱정되시죠? (물론 제 이야기이기도 합니다ㅠㅠ) 책을 읽으려 해도 시간이 없고, 막상 읽어도 어휘력이 느는 것 같지는 않고. 바로 이런 생각에서 ‘어휘역’이 만들어졌어요. 이 게임은 자주 사용하지 않아 잊혀져 가는 단어를 떠올리게 하여 사라져가고 있는 우리의 어휘력을 지키고 강화시켜줍니다. [게임 방법] 우리는 한 단어를 맞혀야 해요. 연상할 수 있는 단어들을 최대한 많이 떠올려 보세요. 추측한 단어가 정답과 얼마나 가까운지를 연관도 점수로 알려드려요. 높은 점수를 받은 단어일수록 정답에 가까운 거죠! 아! 이 게임의 정답과 입력 단어는 ‘명사’로만 제한되어 있어요. 우리가 자주 잊어버리는 단어가 대부분 '명사'이기 때문이죠. [장점] '어휘역'은 단순한 게임을 넘어, 일상에 도움을 줄거에요. 첫째, 다양한 단어를 접하고 사용하면서, 자연스럽게 어휘력이 넓어질 수 있어요. 둘째, 단어들 간의 관계와 유사성을 배워 언어 이해력을 향상시킬 수 있어요. 셋째, 단어의 조합을 고민하며 상상력과 창의적인 사고를 자극해요. 이 게임은 학습과 재미를 결합하여, 자연스럽게 어휘력을 즐겁게 키울 수 있는 환경을 만들어줘요. 어린이부터 어른까지, 모든 사람들에게 적합한 게임이에요. '어휘역'과 함께 단어의 세계를 떠나보세요! ■ 구독 안내 - 구독은 현재 기간이 끝나기 최소 24시간 전에 해지하지 않으면 자동으로 갱신됩니다. 이용약관(EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ 개인정보처리방침: https://sungheelee.notion.site/88718b9dc4704deeaf00f298ca3a0c00
