This is the 6333rd most frequent Korean word.
아니더라도
"Even if not" or "even though it is not."
아니더라도 is used here to imply that something is not absolutely necessary or certain, but the statement after it highlights an important idea regardless.
우리는 성공에 반드시 도달하진 않더라도, 노력은 중요합니다.
Even though we might not necessarily achieve success, effort is important.
아니더라도 is used to contrast the subject's qualities with an extreme characterization but maintains affirmation of their positive actions.
그가 가장 똑똑한 학생은 아니더라도, 그의 노력은 칭찬받아야 합니다.
Even if he is not the smartest student, his effort deserves praise.
아니더라도 serves to moderate the intensity of the statement, balancing it by negating a possible assumption but clarifying the context.
