Session #4. The second letter ‘ah’ has the same radical as the ‘om’ before it but has a subscript vowel mark too. Not sure why it needs that as radicals have an integral ‘ah’ sound. More strange is it has two dots after it. I have asked about them and apparently it’s something to do with transcribing from Sanskrit! I used to think they were a kind of repeat mark but not so. I’ve put some time into learning the alphabet but can’t claim to read or speak Tibetan. I could get by in Ladakhi for a summer, but that was long ago now.
