I know that Aha! moment

I felt a warm rush of gratitude to the speaker, a bespectacled doctor. It made no difference that he was Ayman al-Zawahri, Al Qaeda’s No. 2 man, or that he was threatening to slaughter large numbers of Americans. He spoke a slow, clear fusha, the formal version of Arabic I had been struggling to decipher on the page for 10 hours a day. Even better, his words matched my limited vocabulary: arsala, “to send”; jaish, “army”; raees, “president.” I was almost drunk with exhilaration.
