Both “just” and “only” indicate limitations, but they convey different nuances.

“Just” often suggests a sense of fairness or exactness, focusing on something being sufficient or proper. For instance, “just in time” means at the exact moment needed.

On the other hand, “only” emphasizes exclusivity, underscoring a lack of alternatives. An “only child” highlights that there are no siblings. Understanding their subtleties can enrich one’s communication by adding precision to statements.
