Hindi Orthography in Typing: Matras, Conjuncts and Halant Forms
This domain tests whether the typed copy reproduces Devanagari orthography exactly as printed - every matra in its place, every conjunct in its correct half form, every halant where the language requires it and nowhere else. Orthographic fidelity is where most marks are silently lost.
Matras: watch the two-stroke ones
ो and ौ have no single key on a mechanical Hindi machine; they are built from the ा stroke plus an upper stroke, so they cost two keystrokes and attract errors. Distinguish ु (short, below, hook) from ू (long, below, tail), and remember ृ in words such as कृपा, मृत्यु, पृथ्वी.
Anusvara versus chandrabindu
ं marks nasalisation carried by a consonant: संसार, रंग, हिंदी, अंग. ँ marks a nasalised vowel: आँख, गाँव, माँ, हँसना. Substituting one for the other is a substantive mistake, not a cosmetic slip. Never "correct" the printed passage - reproduce it.
Conjuncts and half forms
Many consonants have dedicated half-form keys (क्, ख्, ग्, च्, ज्, त्, द्, न्, प्, ब्, म्, य्, ल्, व्, श्, स्). Where no half form exists, the halant ् does the work. क्ष, त्र and ज्ञ take the half form plus the second consonant; a full consonant carrying a visible halant is wrong.
Worked example
विद्यार्थी = व + ि + द + ् + य + ा + र + ् + थ + ी. Reasoning: on a machine the ि is struck before द; द uses its half form rather than a halant; the र् is a reph that prints above थ, so the reph stroke must be planned before थ; ी is a post-position matra typed after थ.
Traps
The visible halant where a half form exists; a reph typed after the whole word; a dropped matra inside a dense cluster; inconsistent हिन्दी/हिंदी within the same passage.
