- readings: one spelling, different short vowels (ملک: مَلَک، مَلِک، مِلک، مُلک), each with form, transliteration, IPA, audio and meanings - always: same consonants with other long vowels (consonant-skeleton regex) - not found: inflection stems (آنکھوں -> آنکھ, جاتے -> جانا), prefix regex, trigram similarity - Persian/Arabic words with no Urdu entry: Urdu translations via English first, then English, then their own language; filler glosses (especially, usually…) dropped - punctuation, dashes and spaces dropped from selected words and lookup keys; clean titles Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
