A daily linguistic segment that corrects common mistakes and misconceptions in Arabic usage.

For example, should we say "Affect on  something" or "Affect in  something"? The correct phrase is "Affect in" (أثّر فيه), not "Affect on" (أثّر عليه), as the verb أثّر requires the preposition في.

As Ibn Manzur explained: "Effect (التأثير) is leaving an imprint on something. To ‘affect in’ (أثّر في) means to leave a mark within it."
