So in Urdu language there is no word starting with Ṛe "ڑ" IPA /ɽ/ but I think there may be some words in another language that begins with Ṛe "ڑ" or have similar sound.
In Pashto (Indo-Iranian), the word for ‘blind’ does begin with /ɽ/ and is also written with ‘ڑ’ in some scripts, though most widely accepted scripts use ړ.
- blind: [ɽʉ̃n] (it's also pronounced with [ɻ])
In Sindhi & Shina Abjad, it is written as
ڙ. Example: ڙک
Also Malayalam Abjad seems to have a phoneme for that (
Example: ڔاگی (ṟāgi, meaning finger millet)
Punjabi Shahmukhi also has
ڑ same as in Urdu, similarly but do not have formally have words starting with that phoneme.
In general, most Indo-Iranian languages do not have words that begin with a stressed r (
ṛ). Just like Urdu, the corresponding phoneme in Hindi (Devanagari
ड़) is not used to start any word.
But before the standardization of Urdu, loan words from Sanskrit in Hindustani like ṛ́ṣi (saint) were approximately written in Perso-Arabic as ڑشی, but later removed from Urdu vocabulary.
