सन्धि - AN INTRODUCTION

सन्धि- or संहिता -is the coalescence of two अक्षर occurring immediately one after another. सन्धि does not form a single compound word but reduces the number of syllables. It is necessary :

• When prepositions are used for forming verbs.
• While forming -conjugating- verbs and participles.
• When words are joined together to form समास.
• In declension of nouns and पद.

It occurs in sentences and verses as per the wish of the author.
