Verse:Lõis/Indo-Iranian languages
Sanskrit
Sanskrit in Lõis, unlike in our timeline, is most often written with the Latin alphabet. Its orthography was standardized in the second century AD. Older texts (like the Vedas) use a deeper orthography for Sanskrit, including j̈ for /h/, vowel and semivowel letters used interchangeably (reflecting Sievers' law) and vowel letters <e> and <o> besides <a>. Popular Lõisian English transcriptions like <Jimoleyos> for the Himālayas reflect this more ancient Sanskrit orthography. The modern orthography is used in Sanskrit texts on astronomy like the Súryasidḋánta.

Dialectology
Lõisians use the name "Indic" (Sáinḋavaṁ in Sanskrit) rather than "Sanskrit" to refer to the spoken language.
Lõisian scholars call Vedic Sanskrit "Old Indic" (Puráṙna·sáinḋavaṁ), and unlike in our timeline, more conservative (i.e. less Prakrit-like) dialects were spoken in the first few centuries AD as vernacular languages. The situation was a bit like Arabic dialects in our timeline, with Classical Sanskrit (identical to our timeline) serving as a bridge between the different native dialects.
Most dialects have some innovations traceable to Vedic Sanskrit, like the use of retroflex lateral flaps /ɭ ɭʰ/ for <żd żḋ> (termed "thick D" by phoneticians). Extreme northwestern Sanskrit, though, uses dental fricatives /ð ðʰ/, deriving from a Vedic dialect that used /ɭd ɭdʰ/. /r/ is pronounced as a uvular fricative or trill in some Southern dialects.
The main Prakrits in Lõis are Pali, Gandhari and a variant of Sauraseni, which gave rise to the modern Indic languages in Lõis. They are considered separate languages. In addition, there is a Sanskrit-Greek creole language spoken in Heleasia.
Sample text
From the Rgvaida (in the ancient orthography):
Agnimíżdei purouhitoṁ iojņosio deiuoṁ rtuijaṁ j̈outóroṁ rotnoḋétamoṁ
Avestan
Bactrian
Unlike in our timeline, Bactrian is a living language.
Middle Persian
One Middle Persian dialect in Lõis has /ɭd/ from PIIr *rd, instead of /l/ as in other dialects: guḷd-e-ḷdāḷd "red rose". The Persian dialect spoken in Newton descends from this dialect, and as in Northern Sanskrit, ḷd reflexes as /ð/: gyð ðoð.
