To succeed in something, now especially in academic performance.
"After months of late-night studying, Maria finally achieved a perfect score on her final exam."
In plain English: To achieve means to successfully reach a goal or finish something you worked hard for.
"She worked hard to achieve her goal of becoming a doctor."
Usage: Use "achieve" to describe successfully reaching a specific goal or standard, such as earning high grades or completing a difficult task. It emphasizes the accomplishment of a desired result through effort rather than just the act of trying.
The word achieve comes from the Old French achever, which likely derives from a Late Latin phrase meaning "to reach the head" or "to complete." It entered English through Anglo-Norman with the sense of finishing something successfully.
