Breaking down "manohar" (charming), Prisha thinks it must be consonant sandhi too, since the last…

Why

Prisha is applying the pattern from the previous example without checking what is actually joining here — an overreach similar to ones seen throughout this course. Hindi-Sanskrit sandhi actually has a third major category, alongside vowel and consonant sandhi: विसर्ग संधि (visarga sandhi), which involves the visarga mark (ः) at the end of a word. 'मनोहर' splits as 'मनः' + 'हर' — the visarga in 'मनः', followed by 'ह', changes into 'ओ' under this rule, giving 'मनोहर'. This is neither two vowels merging nor two consonants merging — it's the visarga itself transforming. Test it: this same visarga-to-'ओ' shift is a named, specific rule distinct from both other sandhi types — recognising the visarga mark (ः) at the joining point is the signal to look for this rule, not the consonant-doubling seen in 'सज्जन'. Her brother is right: 'मनोहर' splits as 'मनः+हर' — this is विसर्ग संधि, a third kind, different from both vowel sandhi and consonant sandhi.
