Every word in the Quran traces back to a trilateral Arabic root. We analyzed 1,231 roots across all 6,236 verses and grouped synonymous roots into 39 semantic families — for example, the roots خلق (create), برأ (originate), فطر (bring into being), and صور (fashion) all belong to the Creation family. These families were curated from classical Arabic lexicography (Lane's Lexicon, Maqayis al-Lugha) and validated against the Quranic corpus.
When two families appear in the same verse, that's a thematic bridge. The diagram below maps all such bridges — edge thickness shows co-occurrence strength, and force-directed bundling reveals natural clusters where themes converge.
