I'm following a tutorial for learning to read Devanagari, but I'm finding that I'm having trouble. The letters are presented in what appears to be a "standard order" (my apologies, I don't actually know much about Devanagari yet). However, it seems that some letters both sound the same and have similar symbols. Is there a resource where similar sounding letters are grouped together? I feel that might be easier to learn from. Alternately, some of the letters appear to look very similar but sound different. Is there a resource that groups the letters by shape and not sound?
Devanagari letter has vowels, Consonants and Compound letters.
alpaprāṇa(very little air flow through mouth) and mahāprāṇa(more air flow through mouth) are types of Consonants which are sounds similar for new learner. ex: Ka(क) and kha(ख)
Compound alphabets look similar for new users, ex: letter ka(क) is compound with e becomes ke(कॆ).
