Gurmukhi and Shahmukhi: comparing writing systems

What a Gurmukhi table represents

The Library of Congress’s Panjabi romanization table identifies its subject specifically as Panjabi in Gurmukhi. It lists vowel and consonant correspondences, followed by notes about implicit vowels and nasal signs. A reader can use that table to understand a catalogue spelling, but it is a conversion convention rather than a complete account of how every Punjabi speaker pronounces a text.[1]

The Perso-Arabic comparison

The library’s Urdu table illustrates a different organising problem: letters appear in positional forms, and the notes distinguish consonants, vowel signs and combinations. It is an Urdu convention, not a separate Shahmukhi pronunciation guide. Its usefulness here is comparative: it shows why recognising a Perso-Arabic character may involve more than matching one isolated shape to a Roman letter.[2]

Direction is part of readable text

The W3C’s guidance on mixed-direction text explains why a right-to-left phrase can still contain a left-to-right number or Latin expression. Simply reversing a stored string is not a reliable way to display it. A learner should follow the writing system’s direction while treating a date or an English title inside it according to its own local context.[3]

This matters when two forms sit beside an English explanation. The phrase needs its own direction and isolation so that nearby punctuation stays intelligible. The reading room uses separately marked script fragments for that purpose. Different font shapes are also possible: the underlying text and the way a font draws it are related, but they are not the same thing.[3]

Conversion, pronunciation and meaning

The Library of Congress research guide distinguishes technical romanization, which uses specified correspondences and diacritics, from conventional spellings that may omit them. Transliteration changes written representation; translation supplies meaning in another language. Keeping those tasks separate helps a reader recognise the same work across catalogues without claiming that a Roman spelling fully teaches its pronunciation or translates its contents.[4]
