I dont follow. Why should qualifiers for others affect the choice here? Isnt it better to write Sankara and Sakti with ச (with a qualifier) rather than with ஸ (with a qualifier)?vgvindan wrote:On a second thought, it occurs to me that in regard to श, ச cannot be used because it would have qualifiers for छ झ. That leaves only ஸ.
Yes the alternative is to use the qualifier ONLY when the sound appears against natural rules. Now agreed that with non-tamizh words the sound will appear in more contexts than for tamizh words (like sakala, markaTa, pankajam etc.), but (perhaps ironically) IMHO that is all the more reason for it to be there . If the absence of qualifier can cause confusion because of audience's familiary with langugae rules, then IMO qualifier is a must there.In regard to default sound having no qualifier, I would only say that by introducing a qualifier, we would be cluttering up because the default sound would be the largest used letters.
