In Hindi, adding the virama (्) below ठ creates the half letter ठ् — it silences the inherent 'a' vowel and makes this consonant join the next one without a vowel between them. Ways to write the half letter: 1. Halant form: ठ् (the virama ् appears below the full letter)2. Conjunct form: When ठ् is followed by another consonant, the two letters merge visually into a conjunct (e.g. ठ्क = ठ्क). Some conjuncts develop unique shapes; these are learned as whole units. Example words using ठ्: - ठ्याऊ ('thyaau') — Teaching syllable for ठ् - पठ्यक्रम ('pathyakram') — Syllabus / Curriculum - पाठ्य ('paathya') — Textual / Curricular - ठोठ् ('thoth') — Teaching syllable - पठ्यपुस्तक ('pathyapustak') — Textbook
