The Bṛhatī is a well-known chandas or meter of Vedic Saṁhitās. Out of 14 such Vedic meters, it occupies the 4th place. It has 4 pādas or quarters, with 9 letters in each pāda. According to the sage Śaunaka, as mentioned in his *Chando’nu-kramaṇī*, there are 181 mantras in the *Ṛgveda Saṁhitā* composed in the Bṛhati metre.

*Bṛhatī* is also the name of a well-known commentary by Prabhākara (8th century) on the *Śābara-bhāṣya*, which itself is a commentary by Śabara (57 B.C.) on the famous *Mīmāṁsāsūtras* of Jaimini (200 B. C.).
