Definition
To achieve something is to reach it on purpose and at a cost — to bring a goal all the way to its head after effort, not to stumble into it. The word comes from Old French achever, 'to bring to a head', and that finishing sense still clings to it: you achieve a result, a target, a standard, rarely a small daily act. It implies the climb behind the outcome, which is why we speak of a hard-won achievement and never of achieving breathing.

In TOEFL & IELTS
One of the highest-frequency academic verbs and a natural upgrade from 'get' or 'reach'. It takes goal-like objects: achieve a goal / result / target / standard / consensus / a balance — never 'achieve a problem'. In IELTS Task 2 it powers thesis sentences ('to achieve sustainable growth, governments must…'). Watch the spelling (i before e) and the smooth /tʃ/ start.
