Compare roots
Overlay the chronological distributions of two or more roots (up to six). The shape of how a root appears across the four periods of revelation is often more informative than its raw count — and where several roots all occur in the same verse can be read directly.
● Leeds corpus v0.4.
ℹ How this is computed
● chronological distribution and shared-verse intersection from Leeds morphology + Egyptian Standard (Cairo 1924) revelation order. ~ English meanings beside root names are editorial working glosses for orientation, not cited dictionary definitions.
Type the start of a root (transliteration, Arabic script, or English meaning) into each field, then pick from suggestions. Two roots are enough; add more to overlay them.
Examples worth comparing
- mercy (r-ḥ-m) vs. punishment (ʿ-dh-b). How late-Meccan concentration on mercy contrasts with early-middle emphasis on punishment
- God (a-l-h) vs. Lord (r-b-b). Both ubiquitous, but distributed differently across periods
- faith (a-m-n), works (ʿ-m-l), righteousness (ṣ-l-ḥ). A three-way overlay of a recurring Qur'anic triad — and the verses where all three meet
- faith (a-m-n) vs. disbelief (k-f-r). Counterposed concepts, revealing their proportions by period
Compare passages
Select several passages (up to six) to see which roots they share. Lexical overlap is a starting point, not a conclusion.
Compare surahs
Set two or more surahs (up to six) side by side on their corpus fingerprints — length, vocabulary spread, grammatical texture, and cross-reference reach. Descriptive statistics, not a ranking of merit.
