Devanagari vs Nastaliq: Precision Meets Poetry
One script is an engineer, the other a poet. You should learn to read both.
Devanagari is ruthlessly phonetic. Every vowel has its own sign, long and short are never confused, and what you see is what you say. For a learner, that precision is a gift.
Flip the comparison to consonants, though, and Nastaliq wins where it counts for Perso-Arabic vocabulary: ze, fe, ghain, qaaf, and khe are full citizens of the alphabet rather than dotted afterthoughts. The sounds that Devanagari marks with a fragile nuqta get their own unmistakable letters.
Then there is the sheer pleasure of the page. Nastaliq hangs from its line like calligraphy in motion, each word a small diagonal cascade. Writing it is simply fun in a way that is hard to explain until you try.
Zubane's position: Devanagari's geometry is the engineer, Nastaliq's flow is the poet, and each script teaches you something the other hides. Learn to read both and the whole Hindi-Urdu continuum opens up.
