合理化する

§ Understanding 合理化する

The Japanese verb 合理化する (gourika suru) means 'to rationalize' or 'to streamline operations for efficiency.' It's a compound verb, combining 合理 (gōri), meaning 'reason' or 'rationality,' and 化する (ka suru), a suffix that turns nouns into verbs, often implying a process of 'making something into' or 'changing something into.' In this case, it means 'to make something rational or efficient.'

Meaning
