1.3.42

प्रोपाभ्यां समर्थाभ्याम्

Laghu-siddhāntakaumudī does not carry this rule. It stands in the Aṣṭādhyāyī at 1.3.42, and the abridgement is 1,269 of Pāṇini's 3,983 rules — so this is a place where the poem runs past the textbook.

after क्रम् with प्र or उप in a connected sense, आत्मनेपद is used

The root क्रम् "to step, to stride" after the prefixes प्र or उप takes the आत्मनेपद endings — the middle set — when the prefix carries a sense connected to the act (समर्थ), in the senses of continuance, setting-out and reaching carried down from the earlier rule on क्रम्. So प्रक्रमेथाः "you would set out" conjugates in the middle voice. The derivation names the rule on the silent step where the middle set is chosen. This rule stands outside the Laghu-siddhāntakaumudī abridgement.

• Aṣṭādhyāyī — 1.3.42 प्रोपाभ्यां समर्थाभ्याम्
• Siddhāntakaumudī — outside the Laghu-siddhāntakaumudī abridgement's 1,269 sūtras
