Manava Dharmashastra 1.62

1.62

tānmanūnnāmato nirdiśati | mahātejā iti viśeṣaṇam | anyāni nāmāni rūḍhyā sambandhena vā | vivasvatsuta iti samāsapadarūpaṃ śabdāntaraṃ kṛṣṇasarpanarasiṃhādiśabdavat |

[These six Manus are]—Svārociṣa, Uttama, Tāmasa, Raivata, Cākṣuṣa, and the glorious Vivasvat-suta (the Son of Vivasvat).—(62)

Medhātithi’s commentary (manubhāṣya):
The aforesaid Manus are now mentioned by name.

‘Glorious' is a qualifying epithet.—The other words are names; some being merely conventional, and others based upon relationship; the last name ‘Vivasvat-suta,’ ‘Son of Vivasvat,’ is a different kind of word; it is a name bearing the form of a compound; just like the names ‘Black-serpent,’ ‘Narasiṃha’ (Man-Lion) and the like.
