Key facts

  • Sandhi joins sounds at a boundary; sandhi-viched restores the original meaningful parts and the rule behind the change.
  • The Patwar General Hindi syllabus treats given words' sandhi and sandhi-viched as a direct recognition skill.
  • In swar sandhi, similar vowels usually point to दीर्घ, as in "देव + आलय = देवालय".
  • गुण sandhi commonly changes अ or आ with इ or उ family vowels into ए or ओ, as in "पर + उपकार = परोपकार".
  • वृद्धि sandhi commonly produces ऐ or औ at the boundary, as in "सदा + एव = सदैव".

  4. 4

    गुण sandhi commonly changes अ or आ with इ or उ family vowels into ए or ओ, as in "पर + उपकार = परोपकार".

  5. 5

    वृद्धि sandhi commonly produces ऐ or औ at the boundary, as in "सदा + एव = सदैव".

  6. 6

    यण sandhi changes final इ, ई, उ, ऊ or ऋ into य, व or र before a dissimilar vowel.

  7. 7

    अयादि sandhi restores ए, ऐ, ओ or औ in the first part when forms like अय, आय, अव or आव appear.

  8. 8

    Vyanjan sandhi questions often reveal themselves through doubled consonants, voiced replacements, or anusvar from final म्.

  9. 9

    Visarg sandhi requires restoring "ः" in words such as "मनोभाव", "निराशा" and "दुरुपयोग".

  10. 10

    The correct split must pass two tests at once: phonetic rule and semantic validity.

  11. 11

    Wrong options often copy visible letters from the joined word but fail to restore the actual source word.

  12. 12

    For MCQ speed, split first, check the boundary sounds, identify the rule family, and then eliminate options.

What does sandhi mean in the Patwar General Hindi syllabus?

Sandhi means the sound change that occurs when two sounds meet at a word boundary, and Patwar General Hindi tests whether a candidate can join or split such forms correctly. In Hindi grammar questions, the boundary is usually between two meaningful parts, such as a prefix and a word, two Sanskrit-origin words, or two words used as a compound. Sandhi-viched is the reverse operation: the joined form is broken into its correct original parts and the sound rule is identified. The Patwar General Hindi syllabus treats this as a direct recognition skill: the candidate may be given a joined word and asked for the correct split, or given two parts and asked for the correct joined form. According to the Rajasthan Staff Selection Board's Patwar Direct Recruitment Examination 2019 syllabus, the examination paper was 3 hours long.

The first exam habit is to separate meaning from mere spelling. A word like "paropakar" is not to be split mechanically as "paro + pakar". The meaningful base is "par + upakar", and the sound change is a + u becoming o, so the answer is a gun sandhi split. Similarly, "vidyalaya" is "vidya + alaya", not "vidy + alaya", because the first unit must be a meaningful word. In recognition questions, wrong options often look phonetic but fail the meaning test.

Sandhi is normally grouped into three broad types. Swar sandhi works when vowels meet: deergh, gun, vriddhi, yan and ayadi are the common exam sub-types. Vyanjan sandhi works when consonants meet or when a final consonant changes before the next sound. Visarg sandhi works when the visarg sound changes before a vowel or consonant. Patwar-level questions do not usually require a long theoretical derivation; they require quick recognition of the visible or hearable change at the boundary.

A useful order is: first mark the probable boundary, then name the two sounds at the boundary, then match the change to a rule, and only then pick the option. For example, in "devalaya", the boundary is "deva + alaya" and a + aa gives aa, so it is deergh sandhi. In "mahesh", the boundary is "maha + ish" and aa + i gives e, so it is gun sandhi. In "nayak", the boundary is "nai + ak" and ai becomes ay before the next vowel, so it is ayadi sandhi. This stepwise approach prevents the common mistake of memorising only whole words without knowing why the split works.

For this topic, examples in the English render are transliterated because the surface item is Hindi grammar itself, not an English vocabulary list. The explanation may be in English, but the actual tested words such as "suryoday", "sadachar", "nihshabd" and "yadyapi" must still be treated as Hindi forms; if the candidate treats them as ordinary English spellings, the boundary sound and the grammar rule become harder to see. The safe method is to read the transliteration as a pointer to the Hindi sound pattern, restore the two meaningful parts, and then name the sandhi rule.
