Worksheet: सन्धि

स्वर सन्धि refers to the combination of two vowel sounds in Sanskrit grammar, leading to a change in pronunciation or form. It is primarily divided into three types: दीर्घ सन्धि, गुण सन्धि, and वृद्धि सन्धि. दीर्घ सन्धि occurs when two similar short or long vowels combine to form a longer vowel, e.g., अ + अ = आ. गुण सन्धि involves the combination of अ or आ with इ or ई to form ए, e.g., अ + इ = ए. वृद्धि सन्धि is when अ or आ combines with ए or ऐ to form ऐ, e.g., अ + ए = ऐ. These rules are fundamental in Sanskrit for correct pronunciation and word formation.

वृद्धि सन्धि is a type of vowel sandhi where अ or आ combines with ए or ऐ to form ऐ, and अ or आ combines with ओ or औ to form औ. For example, मम + एव = ममैव, where अ + ए = ऐ. Similarly, जल + ओर: = जलौर:, where अ + ओ = औ. This sandhi is crucial for understanding how vowels merge in Sanskrit to form new sounds, affecting the pronunciation and meaning of words.

यण् सन्धि occurs when इ, उ, ऋ, or लृ is followed by a dissimilar vowel, leading to the replacement of the first vowel with य्, व्, र्, or ल् respectively. For instance, नदी + आवेग: = नद्यावेग:, where इ is replaced by य् before आ. Similarly, सु + आगतम् = स्वागतम्, where उ is replaced by व् before आ. This sandhi simplifies pronunciation by transforming the vowel into a semi-vowel when followed by a different vowel.

गुण सन्धि involves the combination of अ or आ with इ or ई to form ए, and अ or आ with उ or ऊ to form ओ. For example, देव + इन्द्र: = देवेन्द्र:, where अ + इ = ए. Another example is गण + ईश: = गणेश:, where अ + ई = ए. Similarly, नर + उत्तम: = नरोत्तम:, where अ + उ = ओ. This sandhi is essential for understanding how certain vowel combinations in Sanskrit lead to the formation of new vowel sounds.

दीर्घ सन्धि occurs when two similar short or long vowels combine to form a longer vowel. For example, अ + अ = आ, as in पुस्तक + आलय: = पुस्तकालय:. Similarly, इ + इ = ई, as in नगरी + इन्द्र: = नगरीन्द्र:, and उ + उ = ऊ, as in सु + उक्त: = सूक्त:. This sandhi rule is fundamental for vowel elongation in Sanskrit, affecting word pronunciation and meaning.

विसर्ग सन्धि involves the transformation of the विसर्ग (:) when it is followed by certain consonants or vowels. For example, तप: + वनम् = तपोवनम्, where विसर्ग changes to ओ before व. Another example is नम: + ते = नमस्ते, where विसर्ग changes to स before त. This sandhi is crucial for understanding how the विसर्ग adapts based on the following sound, ensuring smooth pronunciation in Sanskrit.

अयादि सन्धि occurs when ए, ऐ, ओ, or औ is followed by a vowel, leading to the replacement of the first vowel with अय्, आय्, अव्, or आव् respectively. For example, ने + अनम् = नयनम्, where ए is replaced by अय् before अ. Similarly, पौ + अक: = पावक:, where औ is replaced by आव् before अ. This sandhi is important for understanding how certain vowel combinations transform into semi-vowel and vowel sequences.

पूर्वरूप सन्धि occurs when ए or ओ is followed by अ, leading to the retention of the ए or ओ and the अ becoming latent, marked by an avagraha (ऽ). For example, हरे + अव = हरेऽव, where ए + अ becomes एऽ. Similarly, गोपालो + अहम् = गोपालोऽहम्, where ओ + अ becomes ओऽ. This sandhi is significant for understanding how certain vowel combinations preserve the first vowel while the second becomes latent.

प्रगृह्य संज्ञा refers to certain words that do not undergo sandhi when followed by a vowel. These words typically end in ई, ऊ, or ए in their dual forms. For example, कवी + इच्छति = कवी इच्छति, where no sandhi occurs. Similarly, विष्णू + इमौ = विष्णू इमौ. This concept is important for identifying exceptions to sandhi rules in Sanskrit, where certain words retain their original form despite being followed by a vowel.

पररूप सन्धि occurs when अ in an upasarga combines with ए or ओ from the following word, leading to the retention of ए or ओ. For example, उप + एजते = उपेजते, where अ + ए = ए. Similarly, उप + ओषति = उपोषति, where अ + ओ = ओ. This sandhi is a specific exception to वृद्धि सन्धि, where the अ in upasargas does not combine with ए or ओ to form ऐ or औ.

स्वर सन्धि occurs between two vowel sounds where they combine to form a new vowel sound. For example, विद्या + आलयः = विद्यालयः. व्यञ्जन सन्धि occurs between a consonant and a vowel or two consonants, leading to changes in the consonant sound. For example, तत् + जनः = तज्जनः. The main difference is the nature of the sounds involved and the rules governing their combination.

दीर्घ सन्धि involves the combination of two similar short or long vowels into a single long vowel. The rule is अकः सवर्णे दीर्घः. For example, देव + आलयः = देवालयः, where अ + आ = आ. Another example is नदी + ईशः = नदीशः, where ई + ई = ई.

गुण सन्धि occurs when अ or आ combines with इ or ई to form ए, or with उ or ऊ to form ओ. For example, देव + इन्द्रः = देवेन्द्रः. वृद्धि सन्धि occurs when अ or आ combines with ए or ऐ to form ऐ, or with ओ or औ to form औ. For example, मम + एव = ममैव. The key difference is the resultant vowel formed by the combination.

यण् सन्धि occurs when इ, उ, ऋ, or लृ is followed by a dissimilar vowel, and the former is replaced by य्, व्, र्, or ल् respectively. For example, इति + आदि = इत्यादि, where इ + आ = य् + आ. This सन्धि is significant as it simplifies pronunciation and maintains the flow of speech.

अयादि सन्धि occurs when ए, ऐ, ओ, or औ is followed by a vowel, leading to the replacement by अय्, आय्, अव्, or आव् respectively. For example, ने + अनम् = नयनम्, where ए + अ = अय् + अ. This सन्धि is crucial in forming compound words and maintaining phonetic harmony.

पूर्वरूप सन्धि occurs when ए or ओ is followed by अ, and the combination retains the ए or ओ, with अ becoming latent, marked by an avagraha (ऽ). For example, हरे + अव = हरेऽव. An exception is when the following अ is part of a prefix or a separate word, where the सन्धि may not apply.

प्रगृह्य संज्ञा refers to certain words that do not undergo सन्धि when followed by a vowel. For example, कवी + इच्छति = कवी इच्छति, where no सन्धि occurs. This exception is important in maintaining the original form of certain words in specific contexts.

पररूप सन्धि occurs when an उपसर्ग ending in अ is followed by ए or ओ, and the combination results in ए or ओ. For example, उप + एजते = उपेजते. This सन्धि is specific to उपसर्ग and helps in forming derived words smoothly.

विसर्ग सन्धि involves the changes to विसर्ग (ः) when followed by certain sounds. रुत्व occurs when विसर्ग becomes र्, सत्व when it becomes स्, and षत्व when it becomes ष्. For example, तपः + वनम् = तपोवनम् (रुत्व), दुः + कर्म = दुष्कर्म (षत्व). These variations depend on the following sound and the preceding vowel.

अनुस्वार (ं) is a nasal sound that replaces म् at the end of a word before a consonant. For example, अहम् + गच्छामि = अहं गच्छामि. It plays a crucial role in सन्धि by ensuring smooth transition between words and maintaining nasalization where required.

स्वर सन्धि refers to the combination of two vowel sounds in Sanskrit. It is crucial for understanding the fluidity and phonetic harmony in the language. Examples include अ + इ = ए (गण + ईश: = गणेश:). Its importance lies in maintaining the euphony of the language and is a fundamental rule in Sanskrit grammar.

गुण सन्धि occurs when अ or आ is followed by इ or ई, resulting in ए (अ/आ + इ/ई = ए), e.g., देव + इन्द्र: = देवेन्द्र:. वृद्धि सन्धि happens when अ or आ is followed by ए or ऐ, resulting in ऐ (अ/आ + ए/ऐ = ऐ), e.g., एक + एकम् = एकैकम्. The key difference is in the resulting vowel and the preceding conditions.

यण् सन्धि applies when इ, उ, ऋ, or लृ is followed by a dissimilar vowel, resulting in य्, व्, र्, or ल् respectively. For example, इति + आदि = इत्यादि (इ → य्), अनु + अस्ति = अन्वस्ति (उ → व्). This rule ensures smooth phonetic transition between vowels.

विसर्ग सन्धि involves the transformation of विसर्ग (:) when followed by certain consonants or vowels. For example, तप: + वनम् = तपोवनम् (विसर्ग becomes ओ). It's significant for maintaining phonetic harmony and is a key aspect of Sanskrit sandhi rules.

पररूप सन्धि occurs when the final अ of an उपसर्ग combines with ए or ओ of the following word, resulting in ए or ओ. For example, उप + एजते = उपेजते. It's crucial in forming meaningful compound words in Sanskrit.

पूर्वरूप सन्धि involves the merging of ए or ओ followed by अ into ए or ओ with an avagraha (ऽ), e.g., गङ्गे + अत्र = गङ्गेऽत्र. Exceptions include cases where the following अ is not merged, maintaining the original form.

श्चुत्व सन्धि involves the transformation of स् or त् to श् or च् when followed by certain consonants. For example, मनस् + चलति = मनश्चलति (स् + च = श्च). This rule is essential for consonant harmony in Sanskrit.

ष्टुत्व सन्धि occurs when स् or त् changes to ष् or ट् before certain consonants, e.g., रामस् + षष्ठ: = रामष्षष्ठ:. It plays a vital role in maintaining the phonetic flow and is a key aspect of Sanskrit sandhi rules.

जश्त्व सन्धि involves the change of झल् letters to जश् letters at the end of a word when followed by a vowel. For example, वाक् + ईश: = वागीश: (क् → ग्). This rule is crucial for phonetic harmony in Sanskrit word formation.

अयादि सन्धि applies when ए, ऐ, ओ, or औ is followed by a vowel, resulting in अय्, आय्, अव्, or आव् respectively. For example, नै + अक: = नायक: (ऐ → आय्). It's important for understanding complex vowel combinations in Sanskrit.
