Sandhi and sandhi-vichchhed

Sandhi is the sound change that takes place when two sounds meet at a boundary, while sandhi-vichchhed is the reverse process of splitting the joined form back into its original parts and explaining the sound change. In Hindi grammar questions, the boundary may be between two words, a prefix and a word, a stem and a suffix-like element, or two parts of a compound expression. The visible result is a joined form such as devi + alay becoming devalay, maha + indra becoming mahendra, or su + agat becoming svagat. Sandhi-vichchhed is not a loose spelling split; it must recover the meaningful components and the rule that joined them. The Rajasthan Staff Selection Board's LDC/Junior Assistant syllabus states that Paper II carries 100 marks. Because the LDC syllabus names sandhi and sandhi-vichchhed directly, preparation should not stop at memorising examples. A candidate must be able to form a word, split a word, and identify the kind of sandhi used.

The basic method is to locate the junction. In devalay, the useful boundary is dev + alay; a + a has produced a long a sound, so the joined form has a long vowel at the meeting point. In mahesh, the useful boundary is maha + ish; a + i has produced e, so it is a guna-type vowel change. In ityadi, the boundary is iti + adi; i followed by a gives y before the next vowel, so the visible form contains ty. If the boundary is located incorrectly, every later step becomes unreliable. Do not split a familiar word merely because it contains a convenient letter sequence. Sandhi-vichchhed must give meaningful components, accepted spelling, and a valid sound rule.

There are three large examination categories: svar sandhi, vyanjan sandhi and visarga sandhi. Vowel sandhi occurs when vowels meet and the result changes the vowel shape, as in a + a = long a, a + i = e, a + e = ai, i + a = ya, or e + a = aya in suitable contexts. Consonant sandhi occurs when a consonant at the junction changes because of the following sound, as in jagat + ish becoming jagadish. Visarga sandhi occurs when final visarga changes, disappears, or affects the next sound, as in manah + rath becoming manorath. In compact MCQs, the question may ask only for the sandhi type, so the first classification step is crucial.

Sandhi formation and sandhi-vichchhed are mirror skills. To form sandhi, first write the last sound of the first part and the first sound of the second part. Then apply the rule and join the remaining letters. To split sandhi, first identify the changed sound in the joined word, then test possible original pairs. For mahotsav, the visible ho points to maha + utsav because a + u gives o under guna sandhi. For nayan, the visible aya points to ne + an in a traditional ayadi explanation only if both parts are meaningful in that context; in ordinary vocabulary, nayan may simply be a base word, so forced splitting is wrong. Examination items generally give either the split expression or a word whose accepted split is standard.

The common notation in study material is first part + second part = sandhi form. In the exam, the same idea may appear as a split form with four close options, a joined word with four possible splits, or a word with four possible sandhi types. A fifth unattempted option may also appear in the broader RSSB objective pattern, but the grammar choice still depends on the same rule. The options are often close orthographic variants: one may double a vowel wrongly, one may keep the halant wrongly, one may use the wrong matra, and one may form a real-looking but invalid word. Treat the script carefully because a one-matra difference can change the answer.

Frequent mistakes are predictable. First, candidates confuse spelling convention with the sandhi rule; not every long vowel in a word is the result of deergha sandhi. Second, they classify by the final word meaning instead of the junction sound. Third, they memorise one example but fail when the same rule appears in a new word. Fourth, they ignore visarga and halant signs, though these are exactly where vyanjan and visarga questions become easy. A good solving routine is: identify the meaningful parts, isolate the two meeting sounds, apply or reverse the sound rule, then name the sandhi type. If any one of these four steps fails, the option should be treated with suspicion. For revision, keep the rule, the accepted split and the final spelling together in the same line; learning only the final word makes distractors harder to eliminate. In exam practice, the safest answer is the option that explains both the sound change and the meaningful components, not merely the option that looks familiar.
