Question

difference between upsarg and pratyay

Answer 1

उपसर्गs are prefix whereas प्रत्येयs are suffix. Normally उपसर्गs are used to show the negativity. And one more main rule that after separating main word from उपसर्ग/प्रत्येय the main word should have a proper meaning. Eg..उपसर्ग : कु: कु + पुत्र = कुपुत्र अ: अ + संभव = असंभव प्रत्येय : कार: िचत्र + कार = िचत्रकार त्व: ममता + त्व = ममत्व
